CryoCompound freezing medium is an aqueous based frozen tissue embedding medium designed to support tissue blocks in cryostat sectioning. Formulated to promote rapid freezing, enhanced sectioning and consistent results at a working temperature of -20° C. The ready-to-use Cryocompound is available in different colors: MON-APP900C (Transparant/colorless), MON-APP900B (Blue), MON-APP900Y (Yellow), MON-APP900O (Orange), MON-APP900G (green), MON-APP900R (Red) or Multicolorkit MON-APP900BYGR (Blue, Yellow, Green, Red).
Principle of method:
Freezing medium
Reagents provided:
100 ml Cryocompound, freezing medium (ready-to-use)
Storage and handling:
Store at room temperature
Procedure:
1. Place few drops of CryoCompound (depends on the size of the sample to be embedded) onto the center of the bottom of cryomold. Be careful to select the proper size embedding mold according to the size of the sample to be embedded. 2. Try to avoid the formation of air bubbles. Remove any bubbles inside the CryoCopound. This is important because the air bubbles will create problems when cutting sections. Air bubbles create freeze- thaw-freeze cycle and ice crystal will form inside of it and result in a very bad morphology due to the ice crystal artefact. 3. Let it settle for 15-30 seconds to allow the CryoCompound to completely wet the surface of the tissue. Hardening of the CryoCompound included the sample (it will happen in 0.5-1 minute) before preparing the CryoCompoundsample-block.

AEC Single Solution is a ready-to-use solution intended for immunohistochemical and in situ-hybridisation staining procedures with horse radish peroxidase (HRP). AEC (3-Amino-9-ethylcarbazol) leads to the formation of a red-brown precipitate at the location of the target antigen or target nucleic acid. The precipitate is insoluble in aqueous mounting media and can be observed by light microscopy. AEC Single Solution is especially useful when a high sensitivity is desired.
The solution should be stored at 2-8°C without furt her dilution. Please store the reagent in a dark place and do not freeze it. Under these conditions the solution is stable up to the expiry date indicated on the label. Do not use product after the expiry date. AEC Single Solution is a ready-to-use solution. Preparation of a working solution as in other chromogenic substrates is not necessary. A positive and a negative control have to be carried out in parallel to the test material. If you observe unusual staining or other deviations from the expected results which could possibly be caused by the kit reagents please contact our technical support.
Reagent preparation:
The solution is ready-to-use. AEC Single Solution can be used directly from the refrigerator and should be stored again at 2-8°C aft er use. When using the small package (8 ml MON-APP169) please directly drop from the bottle. When using the 100 ml package (MON_APP?) please transfer up to 8 ml of the AEC Single Solution into one of the provided dropper bottles. The transferred solution is stable for many weeks if stored at 2-8°C. The vo lume required for several staining runs should be transferred so that the 100 ml stock bottle has to be opened only a few times. If you would like to pipette the solution use a clean vial from which you pipette. Remaining quantities should not be filled back into the bottle but disposed as hazardous material.
Procedure:
1) Rinse the slide with wash buffer after the previous incubation step. 2) Apply the AEC Single Solution to the slide. Incubate for 3-6 minutes. (Incubation time can be extended up to 30 minutes, if desired.) 3) Rinse with distilled H2O. 4) Counterstain with haematoxylin for about 30 seconds up to 5 minutes (depending on the desired staining intensity). 5) Rinse with distilled H2O. 6) Blueing in tap water for at least 5 minutes. 7) Mount with an aqueous mounting medium.
Expected results:
During the reaction of the substrate with horse radish peroxidase in presence of the chromogen AEC, a red-brown precipitate is formed at the location of the target antigen or nucleic acid. The precipitate is insoluble in aqueous solvents and can be observed by light microscopy.
Trouble shooting:
If you observe unusual staining or other deviations from the expected results please read these instructions carefully, or contact our technical support. Also refer to the instructions of the detection systems for guidance on general troubleshooting.
Quality Control:
We recommend carrying out a positive and a negative control with every staining run. The positive control permits the validation of appropriate processing of the sample. If the negative control has a positive result, this points to unspecific staining. Please refer to the instructions of the detection system for guidance on general quality control procedures.
Performance characteristics:
Studies have been conducted to evaluate the performance of the kit reagents. The product has been found to be suitable for the intended use
Limitations of procedure:
Immunohistochemistry is a complex method in which histological as well as immunological detection methods are combined. Tissue processing and handling prior to immunostaining, for example variations in fixation and embedding or the inherent nature of the tissue can cause inconsistent results (Nadji and Morales, 1983). In some tissues endogenous peroxidase activity may cause non-specific staining. The enzyme activity should be blocked by incubation with hydrogen peroxide solution (H2O2 solution). The step is carried out before incubation with primary antibody but after dewaxing and rehydration. Background staining due to endogenous biotin can be blocked through an avidin-biotin blocking step prior to the primary antibody incubation step. The coloured precipitate formed by AEC is soluble in organic solvents. The tissue sections therefore have to be counterstained with aqueous solutions (e. g. Gills or Mayers haematoxylin) and mounted with aqueous mounting media. The colour intensity of the reaction product can decrease with time, especially when exposed to light. The staining reaction itself can be influenced in the same way when carried out in strong light. Sanbio guarantees that the product will meet all requirements described from its shipping date until its expiry date, as long as the product is correctly stored and utilized. No additional guarantees can be given. Under no circumstances shall Sanbio be liable for any damages arising out of the use of the reagent provided
Precautions:
Use by qualified personnel only. AEC (3-Amino-9-ethylcarbazol) and the solvents used are considered hazardous materials. Material safety data sheets (MSDS) are available upon request. Wear protective clothing to avoid contact of reagent or specimen with eye, skin or mucous membrane. In case of reagent or specimen coming into contact with a sensitive area, wash the area with large amounts of water. Oxidising substances, e. g. metals, dust, bacteria or glass devices can influence the stability of AEC Single Solution. Such contaminations have to be avoided. Non-consumed solution needs to be discarded as dangerous substance.

Antibody Diluent is developed for dilution of primary antibodies. Antibodies diluted with Antibody Diluent are primarily used in immunohistochemistry with formalin-fixed paraffin-embedded tissue sections, but also with frozen, HOPE-fixed, and cytological samples as well as in immunoblot procedures.
Antibody diluents used in immunohistochemistry should protect the antibody from microbial contamination and stabilize the antibody chemically. Antibody Diluent reduces non-specific binding of antibodies to tissue sections and is therefore extremely useful in receiving background-free staining results.
Principle of method:
Immunohistochemical staining procedures often start with incubation of a blocking solution to reduce unspecific binding of primary antibody to tissue sections. This step can be omitted if the antibody used is diluted in Antibody Diluent. Antibody Diluent ? minimises unspecific binding of the primary antibody to the tissue section, ? reduces surface tension of the antibody solution and improves spreading the reagent on the slide, ? increases microbial and chemical stability of the antibody, ? reduces adhesion of antibody to the surface of the vial, ? and minimises the danger of antibody degradation by proteolytic enzymes.
Reagents provided:
500 ml Antibody Diluent (ready-to-use)
Storage and handling:
The solution should be stored at 2-8°C without further dilution. Do not freeze it. Under these conditions the solution is stable up to the expiry date indicated on the label. Do not use product after the expiry date. If stored at room temperature the solution is stable for at least 10 month from the date of delivery. A positive and a negative control have to be carried out in parallel to the test material. If you observe unusual staining or other deviations from the expected results which could possibly be caused by this reagent, please contact our technical support.
Expected results:
During the reaction of the substrate with horse radish peroxidase or alkaline phosphatase in the presence of a chromogen, a coloured precipitate is formed at the location of the bound primary antibody. This reaction only takes place if the target antigen is existent in the tissue. The chromogen used determines the colour of the precipitate. The analysis is carried out using a light microscope.
Trouble shooting:
If you observe unusual staining or other deviations from the expected results please read these instructions carefully, contact our technical support. Also refer to the instructions of the detection systems containing Peroxide Block for guidance on general troubleshooting

Performance characteristics:
Studies have been conducted to evaluate the performance of the kit reagents. The product has been found to be suitable for the intended use
Limitations of procedure:
Immunohistochemistry is a complex technique involving both histological and immunological detection methods. It requires a highly trained histotechnologist. Tissue processing and handling prior to immunostaining, for example variations in fixation and embedding or the inherent nature of the tissue can cause inconsistent results (Nadji and Morales, 1983). Inadequate counterstaining and mounting can influence the interpretation of the results.

No additional guarantees can be given. Under no circumstances shall Sanbio be liable for any damages arising out of the use of the reagent provided.
Precautions:
Use through qualified personnel only. Wear protective clothing to avoid contact of reagents and specimens with eye, skin and mucous membranes. If reagents or specimens come in contact with sensitive area, wash with large amounts of water. Microbial contamination of the reagent must be avoided, since otherwise non-specific staining may occur. ProClin300 and sodium azide (NaN3) are used for stabilisation. Reaction of sodium azide with lead or copper in drainage pipes can result in the formation of highly explosive metallic azides. Discard the antibody solution in a large volume of running water to avoid formation of deposits. A material safety data sheet (MSDS) for the pure substances is available upon request.

Tissue processing and handling prior to immunostaining, for example variations in fixation and embedding or the inherent nature of the tissue can cause inconsistent results (Nadji and Morales, 1983). Inadequate counterstaining and mounting can influence the interpretation of the results.Sanbio guarantees that the product will meet all requirements described from its shipping date until its expiry date, as long as the product is correctly stored and utilized. No additional guarantees can be given. Under no circumstances shall Sanbio be liable for any damages arising out of the use of the reagent provided.
Precautions:
Use by qualified personnel only. Wear protective clothing to avoid contact of reagent or specimen with eye, skin or mucous membrane. In case of the reagent or specimen coming into contact with a sensitive area, wash the area with large amounts of water. Microbial contamination of the reagent must be avoided, since otherwise non-specific staining may occur. (NaN3), used for stabilisation, is not considered hazardous material in the concentration used.

Antibody Diluent B is especially developed for dilution of certain primary antibodies. Antibodies diluted with Antibody Diluent B are primarily used in immunohistochemistry with formalin-fixed paraffin-embedded tissue sections, but also with frozen, HOPE-fixed, and cytological samples as well as in immunoblot procedures.
Antibody diluents used in immunohistochemistry should protect the antibody from microbial contamination and stabilize the antibody chemically. Antibody Diluent B reduces non-specific binding of antibodies to tissue sections and is therefore extremely useful in receiving background-free staining results.
Principle of method:
Immunohistochemical staining procedures often start with incubation of a blocking solution to reduce unspecific binding of primary antibody to tissue sections. This step can be omitted if the antibody used is diluted in Antibody Diluent B. Antibody Diluent B minimises unspecific binding of the primary antibody to the tissue section, reduces surface tension of the antibody solution and improves spreading the reagent on the slide, increases microbial and chemical stability of the antibody, reduces adhesion of antibody to the surface of the vial, and minimises the danger of antibody degradation by proteolytic enzymes.
Reagents provided:
25 ml Antibody Diluent B (ready-to-use)
Storage and handling:
The solution should be stored at 2-8°C without furt her dilution. Do not freeze it. Under these conditions the solution is stable up to the expiry date indicated on the label. Do not use product after the expiry date. If stored at room temperature the solution is stable for at least 10 month from the date of delivery. A positive and a negative control have to be carried out in parallel to the test material. If you observe unusual staining or other deviations from the expected results which could possibly be caused by this reagent, please contact our technical support.
Expected results:
During the reaction of the substrate with horse radish peroxidase or alkaline phosphatase in the presence of a chromogen, a coloured precipitate is formed at the location of the bound primary antibody. This reaction only takes place if the target antigen is existent in the tissue. The chromogen used determines the colour of the precipitate. The analysis is carried out using a light microscope.
Trouble shooting:
If you observe unusual staining or other deviations from the expected results please read these instructions carefully, contact our technical support. Also refer to the instructions of the detection systems containing Peroxide Block for guidance on general troubleshooting
Quality Control:
We recommend carrying out a positive and a negative control with every staining run. The positive control permits the validation of appropriate processing of the sample. If the negative control has a positive result, this points to unspecific staining. Please refer to the instructions of the detection system for guidance on general quality control procedures.

The Plus AP Polymer anti-Mouse is designed for the qualitative detection of antigens in fixed paraffin-embedded tissue sections, in frozen tissue sections, and in cytological samples. It is developed for use in combination with monoclonal primary antibodies obtained from mouse. The reagent can be used for examining tissues fixed in different solutions, e.g. formalin (neutrally buffered), B5, Bouin, ethanol, or HOPE.
The purpose of the immunohistochemical staining is to make tissue and cell antigens visible. The Plus AP Polymer anti-Mouse is a highly sensitive detection reagent intended for use in immunohistochemistry and immunocytochemistry. The enzyme polymer in this kit consists of several molecules of secondary antibodies covalently bound to several molecules of alkaline phosphatase (AP). Visualisation occurs via an enzyme-substrate reaction in the presence of a colourising reagent which permits microscopical analysis. The reagent is suitable for the detection of mono- and polyclonal primary antibodies and sera obtained from mouse. In contrast to other detection techniques, which often use the streptavidin-biotin system the Plus AP Polymer anti-Mouse avoids the problem of background staining caused by endogenous biotin in the tissue.
Principle of method:
Paraffin-embedded tissue sections are first deparaffinised and rehydrated. Background staining caused by unspecific binding of the primary antibody or the secondary antibody in the AP polymer is minimized by incubation with a protein blocking solution (Blocking Solution). This step can be omitted if the primary antibodies are diluted in an appropriate buffer. The next step is incubation with the specific primary antibody. After washing, the AP-polymer is applied and incubated. Any excess of unbound AP-polymer is thoroughly washed away after incubation. The addition of the chromogenic substrate starts the enzymatic reaction of the alkaline phosphatase which leads to colour precipitation where the primary antibody is bound. The colour can be observed with a light microscope. The chromogen used determines the colour. The chromogen Fast Red leads to the formation of a magenta-red product of reaction at the place of the target antigen. Other suitable chromogens are Permanent AP Red (magenta-red), New Fuchsin (magenta-red) or NBT (blue-black) with its substrate BCIP.
Reagents provided:
100 ml AP-Polymer anti-Mouse (Ready-to-use) Substrate systems recommended: Permanent AP Red kit, Fast Red substrate kit, New Fuchsin kit. Materials required but not supplied: Positive und negative control tissue Xylene or suitable substitutes Ethanol, distilled H2O Reagents for enzyme digestion or heat pre-treatment Wash buffer PBS or TBS PAP Pen Primary antibody (user-defined) Primary antibody diluent Negative control reagent Chromogenic substrate Counter stain solution Mounting medium Cover slips
Storage and handling:
The solution should be stored at 2-8°C without furt her dilution. Please store the reagent in a dark place and do not freeze it. Under these conditions the solution is stable up to the expiry date indicated on the label. It should not be used after the expiry date. A positive and a negative control have to be carried out in parallel to the test material. If you observe unusual staining or other deviations from the expected results which could possibly be caused by the kit reagents, please contact our technical support.
Reagent preparation:
Reagents should be at room temperature when used. Deparaffinise and rehydrate paraffin-embedded tissue sections. Pre-treatment (optional) with HIER (Heat Induced Epitope Retrieval) or enzymatic digestion. Tissue sections have to be completely covered with the different reagents in order to avoid drying out
Procedure:
1. Blocking Solution (protein block, this step is optional) 5 min. 2. Washing with wash buffer 1 x 2 min. 3. Primary antibody (optimally diluted) or negative control reagent 30-60 min. 4. Washing with wash buffer 3 x 5 min. 5. AP-polymer anti Mouse 30 min. 6. Washing with wash buffer 3 x 2 min. 7. Fast Red, Permanent AP Red, NBT/BCIP or New Fuchsin 5-15 min. (Controlling the colour intensity via light microscope is recommended.) 8. Stopping the reaction with distilled H2O when the desired colour intensity is attained 9. Counterstaining and blueing 10. Mounting: aqueous with Fast Red, permanent with Permanent AP Red, NBT/BCIP or New Fuchsin
Expected results:
During the reaction of the substrate with alkaline phosphatase in the presence of a chromogen, a coloured precipitate is formed at the location of the bound primary antibody. This reaction only takes place if the target antigen is existent in the tissue. The chromogen used determines the colour of the precipitate. The analysis is carried out using a light microscope.
Trouble shooting:
If you observe unusual staining or other deviations from the expected results which could possibly be caused by the reagents, please read these instructions carefully, contact our technical support. No staining on an actually positive control slide: 1. Reagents were not used in the proper order. 2. Chromogenic substrate solution was too old. 3. Bleaching because chromogen and mounting medium are incompatible. 4. The antigen/epitope in the tissue was insufficiently accessible to the primary antibody. Try a pre-treatment such as heat pre-treatment or enzyme digestion. If you used a pre-treatment it should be extended. 5. Primary antibody not from mouse, but from a different species. 6. The antigen/epitope was not stable in the fixation and/or pre-treatment procedure used. Try another fixation or pre-treatment. Weak staining: 1. Inadequate fixation or overfixation. 2. Incomplete deparaffinisation. 3. The antigen/epitope in the tissue was insufficiently accessible to the primary antibody. If you used heat pre-treatment or enzyme digestion it should be extended. 4. Excessive incubation with Blocking Solution or insufficient washing after this step. 5. Too much wash buffer remains on the slides after washing, diluting the reagents applied in the next step. 6. If you are using PBS-based wash buffer: the activity of alkaline phosphatase in the reagents is blocked if too much wash buffer remains on the slides. 7. Incubation times were too short or primary antibody concentration too low. 8. Chromogenic substrate solution was too old. Non-specific background staining or overstaining: 1. Incomplete deparaffinisation. 2. Excessive tissue adhesive on slides. 3. Insufficient washing especially after the incubation with the enzyme polymer or the chromogenic substrate solution. These washings are critical. 4. Tissue was allowed to (partially) dry out with reagents on. 5. Unspecific binding of the primary antibody. Please use a Blocking Solution or dilute the primary antibody in appropriate diluents. 6. Incubation time of the primary antibody was too long or primary antibody concentration too high. 7. Incubation time of the chromogenic substrate solution was too long or reaction temperature too high (e.g. if temperature in the laboratory is high).
Quality Control:
We recommend carrying out a positive and a negative control with every staining run. The positive control permits the validation of appropriate processing of the sample. If the negative control has a positive result, this points to unspecific staining.

Blocking Solution is developed to eliminate unspecific binding of primary and secondary antibodies to tissue sections. It is primarily intended to be used in immunohistochemistry on formalin-fixed paraffin-embedded samples.
Unspecific binding of primary and secondary antibodies to tissue sections in immunohistochemical staining procedures can result in background staining. This effect can be eliminated when tissue sections are incubated with Blocking Solution prior to incubation with the primary antibody. The protein in Blocking Solution abolishes unspecific binding. Blocking Solution is a universal blocking reagent. Unlike other frequently used blocking solutions (e. g. serum blocks) the reagent can be used regardless of the origin species of the secondary antibody. Interferences with secondary antibodies or other components of detection systems are not observed. In contrast to other blocking reagents this Blocking Solution should not be incubated longer than 10 minutes and should be rinsed away with wash buffer. Otherwise the signal intensity of the immunohistochemical staining reaction could be decreased.
Principle of method:
Blocking Solution is applied on tissue sections to reduce background staining due to unspecific binding of primary and secondary antibodies in immunohistochemistry. The step is carried out prior to incubation with the primary antibody
Reagents provided:
100 ml Blocking Solution (ready-to-use)
Storage and handling:
The solution should be stored at 2-8°C without further dilution. Please store the reagent in a dark place and do not freeze it.

DAB Substrate kit is intended for immunohistochemical and in situ-hybridisation staining procedures with horse radish peroxidase (HRP). DAB (3,3-Diaminobenzidine) leads to the formation of a brown precipitate at the location of the target antigen or target nucleic acid. The precipitate is insoluble in aqueous and organic solvents and can be observed by light microscopy.
3 ml DAB Chromogen (liquid DAB concentrate) 11 x 5 ml DAB Substrate Buffer
Storage and handling:
The solutions should be stored at 2-8°C without fur ther dilution. Please store the reagents in a dark place and do not freeze them. Under these conditions the solutions are stable up to the expiry date indicated on the label. Do not use product after the expiry date. The working solution should be prepared freshly at the day of use. Once the two reagents are combined, the resulting solution can be used for up to six hours. Excess working solution needs to be disposed as hazardous substance. A positive and a negative control have to be carried out in parallel to the test material. If you observe unusual staining or other deviations from the expected results which could possibly be caused by the kit reagents please contact our technical support.
Reagent preparation:
Add 4 drops of DAB Chromogen (DAB concentrate) to one bottle of DAB Substrate Buffer and mix thoroughly.
Procedure:
1) Rinse the slide with wash buffer after the previous incubation step. 2) Apply the DAB working solution onto the slide. Incubate for 5-15 minutes. 3) Rinse with distilled H2O. 4) Counterstain with haematoxylin for about 30 seconds up to 5 minutes (depending on the desired staining intensity). 5) Rinse with distilled H2O. 6) Blueing in tap water for at least 5 minutes. 7) Dehydrate through a graded series of ethanol and clear in xylene. Mount with a permanent mounting medium. Note: It is also possible to mount DAB with aqueous mounting media.
Expected results:
During the reaction of the substrate with horse radish peroxidase in presence of the chromogen DAB, a brown precipitate is formed at the location of the target antigen or nucleic acid. The precipitate is insoluble in aqueous and organic solvents and can be observed by light microscopy.
Trouble shooting:
If you observe unusual staining or other deviations from the expected results please read these instructions carefully, or contact our technical support. Also refer to the instructions of the detection systems for guidance on general troubleshooting.
Quality Control:
We recommend carrying out a positive and a negative control with every staining run. The positive control permits the validation of appropriate processing of the sample. If the negative control has a positive result, this points to unspecific staining. Please refer to the instructions of the detection system for guidance on general quality control procedures.
Performance characteristics:
Studies have been conducted to evaluate the performance of the kit reagents. The product has been found to be suitable for the intended use
Limitations of procedure:
Immunohistochemistry is a complex method in which histological as well as immunological detection methods are combined. Tissue processing and handling prior to immunostaining, for example variations in fixation and embedding or the inherent nature of the tissue can cause inconsistent results (Nadji and Morales, 1983). In some tissues endogenous peroxidase activity may cause non-specific staining. The enzyme activity should be blocked by incubation with hydrogen peroxide solution (H2O2 solution). The step is carried out before incubation with primary antibody but after dewaxing and rehydration. Background staining due to endogenous biotin can be blocked through an avidin-biotin blocking step prior to the primary antibody incubation step. Inadequate counterstaining and mounting can influence the interpretation of the results. Sanbio guarantees that the product will meet all requirements described from its shipping date until its expiry date, as long as the product is correctly stored and utilized. No additional guarantees can be given. Under no circumstances shall Sanbio be liable for any damages arising out of the use of the reagent provided.

The Fast AP One-Step Polymer anti-Mouse/Rabbit is designed for the qualitative detection of antigens in fixed paraffin-embedded tissue sections, in frozen tissue sections, and in cytological samples. It was developed for use in combination with mono- and polyclonal primary antibodies and sera obtained from mice or rabbit. The kit can be used for examining tissues fixed in different solutions, e.g. formalin (neutrally buffered), B5, Bouin, ethanol, or HOPE. It is intended for in vitro diagnostic use.
The purpose of the immunohistochemical staining is to make tissue and cell antigens visible. The Fast AP One-Step Polymer anti-Mouse/Rabbit is a highly sensitive detection reagent intended for use in immunohistochemistry and immunocytochemistry. The enzyme polymer consists of several molecules of secondary antibodies covalently bound to several molecules of alkaline phosphatase (AP). Visualisation occurs via an enzymesubstrate reaction in the presence of a colorising reagent which permits microscopical analysis. The test system is suitable for the detection of mono- and polyclonal primary antibodies and sera obtained from mice or rabbit. Cross-reactivity with primary antibodies from rat has been observed. In contrast to other detection techniques, which often use the streptavidin-biotin system the Fast AP One-Step Polymer anti-Mouse/Rabbit avoids the problem of background staining caused by endogenous biotin in the tissue.
Principle of method:
Paraffin-embedded tissue sections are first deparaffinised and rehydrated. Background staining caused by unspecific binding of the primary antibody or the secondary antibody in the AP OneStep Polymer is minimized by incubation with a protein blocking solution. This step can be omitted if the primary antibodies are diluted in an appropriate buffer. The next step is incubation with the specific primary antibody. After washing, the AP One-Step Polymer is applied and incubated. Any excess of unbound polymer is thoroughly washed away after incubation. The addition of the chromogenic substrate starts the enzymatic reaction of the alkaline phosphatase which leads to colour precipitation where the primary antibody is bound. The colour can be observed with a light microscope. The chromogen used determines the colour. The chromogen Permanent AP Red leads to the formation of a magentared product of reaction at the place of the target antigen.
Reagents provided:
100 ml Fast AP One-Step Polymer anti-Mouse/Rabbit (ready-to-use) Substrate systems recommended: Permanaent AP Red kit Materials required but not supplied Positive and negative control tissue Xylene or suitable substitutes Ethanol, distilled H2O Reagents for enzyme digestion or heat pre-treatment Wash buffer PBS or TBS Blocking Solution (for protein blocking, optional) Pink PAP Pen Primary antibody (user-defined) Primary antibody diluent Negative control reagent Chromogenic substrate Counter stain solution Mounting medium Cover slips
Storage and handling:
The solution should be stored at 2-8°C without further dilution. Please store the reagent in a dark place and do not freeze it. Under these conditions the solution is stable up to the expiry date. It should not be used after the expiry date. A positive and a negative control have to be carried out in parallel to the test material. If you observe unusual staining or other deviations from the expected results which could possibly be caused by the reagent, please contact our technical support
Reagent preparation:
Reagents should be at room temperature when used. Deparaffinise and rehydrate paraffin-embedded tissue sections. Pre-treatment (optional) with HIER (Heat Induced Epitope Retrieval) or enzymatic digestion. Tissue sections have to be completely covered with the different reagents in order to avoid drying out.

(Controlling the colour intensity via light microscope is recommended.) 8. Stopping the reaction with distilled H2O when the desired colour intensity is attained 9. Counterstaining and blueing 10. Mounting: permanent or aqueous with Permanent AP Red Kit
Expected results:
During the reaction of the substrate with alkaline phosphatase in the presence of a chromogen, a coloured precipitate is formed at the location of the bound primary antibody. This reaction only takes place if the target antigen is existent in the tissue. The chromogen used determines the colour of the precipitate. The analysis is carried out using a light microscope.
Trouble shooting:
If you observe unusual staining or other deviations from the expected results which could possibly be caused by the reagents, please read these instructions carefully, contact our technical support. No staining on an actually positive control slide: 1. Reagents were not used in the proper order. 2. Chromogenic substrate solution was too old. 3. Bleaching because chromogen and mounting medium are incompatible. 4. The antigen/epitope in the tissue was insufficiently accessible to the primary antibody. Try a pre-treatment such as heat pre-treatment or enzyme digestion. If you used a pre-treatment it should be extended. 5. Primary antibody not from mouse or rabbit but from a different species. 6. The antigen/epitope was not stable in the fixation and/or pre-treatment procedure used. Try another fixation or pre-treatment. Weak staining: 1. Inadequate fixation or overfixation. 2. Incomplete deparaffinisation. 3. The antigen/epitope in the tissue was insufficiently accessible to the primary antibody. If you used heat pre-treatment or enzyme digestion it should be extended. 4. Excessive incubation with Blocking Solution or insufficient washing after this step. 5. Too much wash buffer remains on the slides after washing, diluting the reagents applied in the next step. 6. Incubation times were too short or primary antibody concentration too low. 7. Chromogenic substrate solution was too old. Nonspecific background staining or overstaining: 1. Incomplete deparaffinisation. 2. Excessive tissue adhesive on slides. 3. Insufficient washing especially after the incubation with the enzyme polymer or the chromogenic substrate solution. These washings are critical. 4. Tissue was allowed to (partially) dry out with reagents on. 5. Unspecific binding of the primary antibody. Please use Blocking Solution or dilute the primary antibody in appropriate diluents. 6. Incubation time of the primary antibody was too long or primary antibody concentration too high. 7. Incubation time of the chromogenic substrate solution was too long or reaction temperature too high (e.g. if temperature in the laboratory is high).
Quality Control:
We recommend carrying out a positive and a negative control with every staining run. The positive control permits the validation of appropriate processing of the sample. If the negative control has a positive result, this points to unspecific staining.

Fast Enzyme is a ready-to-use solution developed for enzymatic epitope retrieval on formalin-fixed tissue sections on slides. This procedure (sometimes called PIER, Protease Induced Epitope Retrieval) is primarily used in immunohistochemical staining procedures. Proteolytic pre-treatment is also used in in situ-hybridisation. Fast Enzyme is intended for research use only.
Immunohistochemical staining procedures consist of sequential incubation steps with blocking solutions, antibodies and secondary reagents, enzymes and chromogenic substrates carried out on tissue sections. These tissue sections are mostly prepared out of formalin-fixed paraffin-embedded tissue blocks. Cellular structures are very effectively stabilised by formalin fixation which results in optimal morphological preservation of the sample. On the other hand the formalin fixation leads to strong cross-links between proteins. This means that epitopes of antigens are being masked and often are no longer accessible for primary antibodies. In order to enable primary antibodies to bind to antigens the epitopes have to be recovered. Enzymatic digestion with proteolytic enzymes (PIER) restores structures of the epitopes making them more accessible to specific antibodies. Heat induced epitope retrieval (HIER) in buffer solutions of different compositions and pH-values is another way of recovering epitopes. The primary antibody used determines the appropriate method.
Principle of method:
Fast Enzyme is a ready-to-use enzyme solution for enzymatic epitope retrieval.
Reagents provided:
15 ml Fast Enzyme (Ready-To-Use)
Storage and handling:
The solution should be stored at 2-8°C without further dilution. Under these conditions the solution is stable up to the expiry date indicated on the label. Do not use product after the expiry date. A positive and a negative control have to be carried out in parallel to the test material. If you observe unusual staining or other deviations from the expected results which could possibly be caused by this reagent, please contact our technical support.
Reagent preparation:
The solution is ready-to-use.
Procedure:
Fast Enzyme is suitable for enzymatic epitope retrieval carried out after the dewaxing and rehydration of the tissue sections. 1. Cover deparaffinised and rehydrated tissue sections with ready-to-use Fast Enzyme Solution. 2. Incubate for 5 minutes at room temperature. (It was shown that in individual cases a stronger signal can be obtained when the incubation time is elongated. Usually an incubation for 5 min at room temperatur is sufficient.) 3. Rinse carefully (3 x) with wash buffer. 4. Proceed with immunohistological staining as usual.
Expected results:
During the reaction of the substrate with horse radish peroxidase or alkaline phosphatase in the presence of a chromogen, a coloured precipitate is formed at the location of the bound primary antibody. This reaction only takes place if the target antigen is existent in the tissue. The chromogen used determines the colour of the precipitate. The analysis is carried out using a light microscope.
