The wash Buffer is designed as washing solution for immunohistochemical and immunocytological staining procedures on slides. Wash Buffer is primarily used with formalin-fixed paraffin-embedded tissue sections, but also with frozen, HOPE-fixed, and cytological samples as well as in immunoblot procedures. The Wash Buffer is suitable for manually operated and automated immunohistochemical staining.
Immunohistochemical staining procedures consist of sequential incubation steps with blocking solutions, antibodies and secondary reagents, enzymes and chromogenic substrates carried out on tissue sections. Washing away the applied reagents after each incubation step is critical to receive optimally stained samples. The Wash Buffer is especially designed for effective washing and therefore ensures brilliant staining results.
Principle of method:
The Wash Buffer is a 20fold concentrated phosphate buffer with additives of sodium chloride, detergent, and stabilising substances. For preparation of the working strength solution the buffer concentrate is diluted 1:20 with deionised or distilled water. The resulting solution has a pH of 7.2 (7.0 to 7.4). The Wash Buffer is wetting the tissue sections with detergent and thus reduces surface tension and improves spreading the reagents on the tissue section, reduces unspecific binding of reagents on the tissue sample, and because of the exact tuned salt concentration effects an excellent preservation of cell morphology.
Reagents provided:
2500 ml Wash Buffer (20fold concentrated, adequate for 50 litres ready-to-use wash buffer)
Storage and handling:
The solution should be stored at room temperature. It is stable up to the expiry date indicated on the label if undiluted. Do not use product after the expiry date. The diluted working strength solution is stable for about 1 week depending on the ambient temperature. 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:
Preparation of the Wash Buffer working strength solution: Dilute Wash Buffer concentrate 1:20 with deionised or distilled water and mix thoroughly. The pH-value should be at 7.2 (7.0 to 7.4). If necessary adjust pH-value with diluted NaOH or HCl solution.
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, 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 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. The Wash Buffer is a 20fold concentrated solution with a mildly acidic pH-value. The correct pHvalue of about 7.0 (+/- 0.2) is achieved after diluting the solution 1:20. Sometimes deionised water has pH-values considerably different from the neutral point (pH 7.0) depending on the preparation method. Experiments have shown that the Wash Buffer can successfully be diluted with deionised or distilled with water in the pH-range of 5.5 up to 9.5. If a detection system with alkaline phosphatase is used please note: larger amounts of wash buffer remaining on the slides can lead to decreasing enzyme activity. 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. ProClin 300 is used for stabilisation. A material safety data sheet (MSDS) is available upon request.
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.

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.

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.

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.
30 ml DAB Chromogen (liquid DAB concentrate) 500 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 50 µl DAB Chromogen (DAB concentrate) to 1 ml of DAB Substrate Buffer and mix thoroughly. Note: Typical working concentrations are 50 µl (0.9 mg) DAB per ml substrate buffer. The colour intensity can be adjusted by decreasing or increasing the DAB concentration in the working solution. Maximum sensitivity in immunohistochemical staining can be achieved by working concentrations of about 80 µl (1.5 mg) DAB per ml substrate buffer.
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.

The Plus AP Polymer anti-Rabbit 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 monoand polyclonal primary antibodies and sera obtained from rabbits. 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-Rabbit 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 rabbits. In contrast to other detection techniques, which often use the streptavidin-biotin system the Plus AP Polymer anti-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 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 Permanent AP Red leads to the formation of a magentared product of reaction at the place of the target antigen.
Reagents provided:
6 ml AP-Polymer anti-Rabbit (Ready-to-use) Substrate systems recommended: Permanent AP Red 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 solutions 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 solutions are stable up to the expiry date indicated on the label. They 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 Rabbit 30 min. 6. Washing with wash buffer 3 x 2 min. 7. Permanent AP Red 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: permanent or aqueous with Permanent AP Red
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 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. 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).

Principle of method:
Paraffin-embedded tissue sections are first deparaffinised and rehydrated. Endogenous peroxidase activity in the tissue may cause non-specific staining.

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). Endogenous peroxidase or pseudoperoxidase activity may cause non-specific staining. The enzyme activity is blocked by incubation with hydrogen peroxide solution. Tissues containing Hepatitis B Surface Antigen (HBsAg) may give false positive results with HRP (horse radish peroxidase) detection systems (Omata et al, 1980). Inadequate counterstaining and mounting can influence the interpretation of the results. The colour intensity of the reaction product can decrease with time, especially when exposed to 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. Wear protective clothing to avoid eye, skin or mucous membrane contact with the reagent. In case of the reagent 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 might appear. ProClin is used for stabilisation. A Material safety data sheet (MSDS) is available upon request.
The Plus HRP Polymer anti-Rabbit is designed for the qualitative detection of antigens in fixed paraffinembedded tissue sections, in frozen tissue sections, and in cytological samples. It is developed for use in combination with mono- and polyclonal primary antibodies and sera obtained from rabbits. 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 HRP Polymer anti-Rabbit 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 horse radish peroxidase (HRP). 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 rabbits. In contrast to other detection techniques, which often use the streptavidin-biotin system the Plus HRP Polymer anti-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. Endogenous peroxidase activity in the tissue may cause non-specific staining. This enzyme activity can be blocked by incubation with 3% H2O2-solution (Peroxide block). Background staining caused by unspecific binding of the primary antibody or the secondary antibody in the HRP 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 HRP-polymer is applied and incubated. Any excess of unbound HRP-polymer is thoroughly washed away after incubation. The addition of the chromogenic substrate starts the enzymatic reaction of the horse radish peroxidase 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 AEC leads to the formation of a red-brown product of reaction at the place of the target antigen. The chromogen DAB forms a dark brown precipitate.
Reagents provided:
100 ml HRP-Polymer anti-Rabbit (Ready-to-use) Substrate systems recommended: Permanent AEC kit, AEC Single Solution, AEC Substrate kit, DAB Substrate kit, DAB High contrast kit Materials required but not supplied: Positive und negative control tissue Xylene or suitable substitutes Ethanol, distilled H2O 3% H2O2 solution 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 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 indicated on the label. They 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. Peroxide blocking (3 % H2O2 solution) 10 min. 2. Washing with wash buffer 1 x 2 min. 3. Blocking Solution (This step is optional.) 5 min. 4. Washing with wash buffer 1 x 2 min. 5. Primary antibody (optimally diluted) or negative control reagent 30-60 min. 6. Washing with wash buffer 3 x 5 min. 7. HRP-polymer anti-Rabbit 30 min. 8. Washing with wash buffer 3 x 2 min. 9. AEC or DAB (Controlling the colour intensity via light microscope is recommended.) 5-15 min. 10. Stopping the reaction with distilled H2O when the desired colour intensity is attained 11. Counterstaining and blueing 12. Mounting: aqueous with AEC, permanent with DAB or Permanent AEC
Expected results:
During the reaction of the substrate with horse radish peroxidase 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 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. 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). 8. The substrate is metabolised by endogenous horse radish peroxidase in the tissue. Maybe the hydrogen peroxide solution used for blocking was inactivated
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.
