Cluster of Differentiation 45 (CD45), also known as Leukocyte Common Antigen (LCA), is a member of the protein tyrosine phosphatase (PTPase) family that is known to regulate a variety of cellular processes including cell growth, differentiation, the mitotic cycle, and oncogenic transformation. CD45 is expressed in most nucleated cells of hematopoietic origin, and is an essential regulator of T- and B-cell antigen receptor signaling. Anti-CD45 positively stains the majority of lymphoid neoplasms, and is highly indicative of lymphoid origin. However, an absence of CD45 does not rule out lymphoid tumours, as certain types of neoplasms lack CD45, such as Hodgkin's lymphoma, some T-cell lymphomas, and some leukemias.

Glypican-3 (GPC3) is a GPI-anchored proteoglycan involved in cell division and growth regulation. Glypican-3 is a useful tumour marker, and its expression has been shown to be upregulated in hepatocellular carcinoma (HCC), hepatoblastoma, melanoma, testicular germ cell tumours, and Wilms' tumour. Patients with HCC have presented elevated levels of GPC3 in the neoplastic liver tissues and serum, levels which are higher than detected in cirrhotic liver or liver with focal lesions, including those with hepatic adenoma and dysplastic nodules. Glypican-3 is also overexpressed in testicular germ cell tumours of certain subtypes, such as yolk sac tumours and choriocarcinoma, and in embryonal tumours.
Actin is part of the cytoskeletal system of every cell type. It can be classified based on isoelectric points as alpha, beta, and gamma. Muscle Specific Actin includes those of the alpha and gamma isotypes. Skeletal, smooth, and cardiac muscle cells will all stain positively with Anti-Muscle Specific Actin, but mesenchymal cells, not including myoepithelium, will stain negatively. Normal and neoplastic non-muscle cells, including vascular endothelial and connective tissues, carcinomas, melanomas, and lymphomas, will also be negative for muscle specific actin. The use of Anti-Muscle Specific Actin in concert with Anti-Smooth Muscle Actin can allow for differentiation between rhabdomyosarcoma and leiomyosarcoma, as muscle specific actin is found in rhabdomyoblasts, while smooth muscle actin is found in leiomyosarcomas.
Cluster of Differentiation 10 (CD10) is a cell surface metalloendopeptidase that cleaves and inactivates several peptide hormones including glucagon, enkephalins, and oxytocin. Also known as Common Acute Lymphoblastic Leukemia Antigen (CALLA), it is an important cell surface marker in the diagnosis of human ALL (Acute Lymphocytic Leukemia), and is found positive in precursor B lymphoblastic leukemia/lymphoma, angioimmunoblastic T-cell lymphoma, Burkitt's lymphoma, and follicular germinal center lymphoma. CD10 expression has also been reported in a variety of non-hematolymphoid tissues, particularly of the kidney. It is a useful aid in the diagnosis of various malignant tumours such as renal cell carcinoma, endometrial stromal sarcoma, and hepatocellular carcinoma.

Cluster of Differentiation 4 (CD4) is a membrane glycoprotein expressed in T helper cells, monocytes, macrophages, granulocytes, and dendritic cells, and is a receptor of human immunodeficiency virus (HIV). CD4 staining is used for identifying lymphoproliferative disorders. Since the majority of peripheral T-cell lymphomas arise from the T helper cell subset, CD4 expression can be found in most forms of T-cell lymphomas as well as anaplastic large T-cell lymphomas and mycosis fungoides. Since CD4 may be aberrantly expressed in neoplastic T-lymphocytes, a panel of markers may be used to identify such tumours. CD4(+) CD25(+) T-cells are reported to exert immunosuppression, which is commonly observed in various types of cancers, including non-small cell lung cancer and cancers of the breast, prostate, and ovary.
Cytokeratin 14 (CK14) is found in squamous epithelial basal cells, myoepithelium, some glandular epithelia, and mesothelial cells. Anti-Cytokeratin 14 is useful for distinguishing squamous cell carcinomas from other epithelial tumours, and for classifying metaplastic breast carcinomas.

Epidermal Growth Factor Receptor (EGFR) is a tyrosine kinase present in gliocytes, epithelial cells, fibroblasts, keratinocytes, and other cell types. EGFR is overexpressed in various cancers including those of the colon, pancreas, oropharynx, stomach, and non–small cell lung, as well as head and neck squamous carcinoma and anal squamous carcinoma. EGFR expression is common in breast cancer, especially in triple-negative and basal-like breast carcinomas, and recent research has also found EGFR expressed in malignant bone and soft tissue cancers. Anti-EGFR is useful for detecting epithelioid and synovial sarcoma.
Fibronectin is a glycoprotein that contributes to cell adhesion, migration, and metastasis. Renal cancer cells exhibit higher expression of fibronectin, therefore Anti-Fibronectin is useful for assessing the progression and aggressiveness of renal cancer cells.
Mucin 5AC (MUC5AC) is a secretory-type mucin found in columnar mucous cells of surface gastric epithelium and in goblet cells of the fetal and precancerous colon, but not in normal colon cells. MUC5AC expression is indicated in carcinomas wherein the type is defined as diffuse and infiltrative, and those located mainly in the antrum. Studies have also suggested a correlation between MUC5AC and colorectal signet ring cell carcinoma, with overexpression of MUC5AC relating to the carcinogenesis, malignant potential, progression, and clinical behaviors.
Napsin A is a pepsin-like aspartic proteinase that is closely related to Napsin B. It is expressed mainly in the lung and kidney, and is involved in the correct folding, targeting, and control of aspartic proteinase zymogens. Napsin A expression has been indicated in type II pneumocytes and adenocarcinomas of the lung and kidney. Anti-Napsin A is also useful for differentiating between primary lung adenocarcinomas and adenocarcinomas of other organs, due to the high expression of Napsin A in adenocarcinomas of the lung.
Parathyroid Hormone (PTH), also known as Parathormone or Parathyrin, is a hormone secreted by the parathyroid glands that functions to increase the concentration of calcium in the blood. Anti-Parathyroid Hormone (PTH) is useful for differentiating parathyroid hyperplasia/neoplasms from thyroid and metastatic neoplasms, and is also used in the consideration of parathyroid carcinomas located primarily in the anterior mediastinum.

Prostatic Specific Acid Phosphatase (PSAP) is a prostatic enzyme found in the glandular epithelium of the prostate. PSAP levels are elevated in hyperplastic prostate and prostate carcinoma, with the highest levels being detected in metastasized prostate cancer. Moderate overexpression of PSAP is also characteristic of diseases of the bone (such as Paget's disease or hyperparathyroidism), diseases of blood cells (such as sickle-cell disease), multiple myeloma, or lysosomal storage diseases (such as Gaucher's disease). PSAP is considered more sensitive, yet less specific, than PSA, however Anti-PSAP can act as a useful complement to Anti-PSA under suitable clinical contexts.
Wilms' Tumour Protein (WT1) is a transcription factor involved in the development of the urogenital system. Anti-WT1 is utilized in the differential diagnosis of pulmonary malignancies (nuclei staining) and small round cell tumours. Ewing's sarcomas, primitive neuroectodermal tumours, neuroblastomas, rhabdomyosarcomas, and rhabdoid tumours do not stain with Anti-WT1, but cytoplasmic staining may be observed. Although lung adenocarcinomas do not exhibit nuclear staining with Anti-WT1, the antibody may stain the cytoplasm. Anti-WT1 also stains serous ovarian carcinomas, but does not stain mucinous carcinomas of the ovary and pancreatobiliary carcinomas.

Clone OX-42 recognises the rat equivalent of human CD11b and shares a common epitope with CB11c (integrin apha M and alpha X chains). (PMID:1672643; Tamatani T et al 1991). CD11b is a single-pass type I membrane protein that belongs to the integrin alpha chain family. CD11b is predominantly expressed in monocytes and granulocytes and is implicated in various adhesive interactions of monocytes, macrophages and granulocytes as well as in mediating the uptake of complement-coated particles (Ref: SWISSPROT). CD11b is also frequently used as a microglial marker allowing to distinguish between quiescent and activated microglia based on the intensity of CD11b staining. Moreover the OX-42 monoclonal antibody specifically binds to the CR3 complement (C3bi) receptor found on most monocytes, granulocytes, macrophages, dendritic cells, and microglia. OX-42 antibody inhibits C3bi binding activity.<br />CD11b, also known as integrin alpha M or Mac-1, and is a component of complement receptor 3 (CR3). CD11c, also known as integrin alpha X, and is a component of complement receptor 4 (CR4). Integrin alpha-X/beta-2 is a receptor for fibrinogen. CD11b and CD11c are expressed on immune cells such as macrophages, monocytes, granulocytes, and dendritic cells. OX42 has also been shown to detect microglia in the brain, as well as cells of the liver and epidermis.

Specificity:
Clone OX-42 recognises the rat equivalent of human CD11b and shares a common epitope with CB11c (integrin apha M and alpha X chains). (PMID:1672643; Tamatani T et al 1991). Immunoprecipitates three polypeptides of 160 kDa, 103 kDa and 95 kDa and a fainter band may also be seen at 133 kDa under non-reducing conditions. If the immunoprecipitated proteins are reduced, two major peptides of 163 kDa and 100 kDa and a minor 135 kDa peptide are seen. Mis-information exists concerning reactivity to mouse and human CD11b/c with OX-42 from various vendors. Biosensis has not verified that OX42 reacts with mouse and human, and ONLY recommends the clone only for rat as the original paper and most papers use the OX family of clones on rat.

Mouse anti-Nestin Monoclonal Antibody (Unconjugated), suitable for WB, ICC.
Background Info:
Nestin is a member of the class IV intermediate filament protein family which is expressed in neuronal stem cells. The molecular weight of human Nestin as determined by SDS-PAGE mobility is about 240 kDa. However the real molecular weight is considerably less than this, at 177 kDa, the disparity being likely due to the highly charged region of the C-terminal segment. Nestin is relatively poorly conserved in protein sequence across species boundaries, so that the mouse and human proteins have an overall identity of only 62%. As a result antibodies to the human protein often fail to recognize the rodent homologue and vice versa. However this antibody stains both rodent and human Nestin. Antibodies to Nestin are widely used to identify neural stem cells.

The amyloid beta peptide is derived from the cleavage of the Amyloid precursor protein (APP) and varies in length from 39 to 43 amino acids. However, the form(s) of amyloid-beta peptide (A? associated with the pathology characteristic of Alzheimer's disease (AD) remains unclear. In particular, the neurotoxicity of intraneuronal A? accumulation is an area of considerable research and controversy principally because antibodies thought to be specific for A? have been shown to actually detect intraneuronal APP and not A? exclusively.<br /><br />MOAB-2 (mouse IgG2b) is a pan-specific, high-titer antibody to A? residues 1-4 as demonstrated by biochemical and immunohistochemical analyses (IHC), and is highly specific just to amyloid beta peptide.<br /><br />MOAB-2 did not detect APP or APP-CTFs in cell culture media/lysates (HEK-APPSwe or HEK APPSwe/BACE1) or in brain homogenates from transgenic mice expressing 5 familial AD (FAD) mutation (5xFAD mice). <br /><br />Using IHC on 5xFAD brain tissue, MOAB-2 immunoreactivity co-localized with C-terminal antibodies specific for A?40 and A?42. MOAB-2 did not co-localize with either N- or C-terminal antibodies to APP. In addition, no MOAB-2-immunreactivity was observed in the brains of 5xFAD/BACE-/- mice, although significant amounts of APP were detected by N- and C-terminal antibodies to APP, as well as by 6E10.<br /><br />In both 5xFAD and 3xTg mouse brain tissue, MOAB-2 co-localized with cathepsin-D, a marker for acidic organelles, further evidence for intraneuronal A?, distinct from A? associated with the cell membrane. MOAB-2 demonstrated strong intraneuronal and extra-cellular immunoreactivity in 5xFAD and 3xTg mouse brain tissues.

Suggested dilution of 1:2000-1:5,000 for WB, standard ECL detection systems. <br><br>Tissue samples for the detection of beta-amyloid should be prepared as detailed in K.L. Youmans et al. {Journal of Neuroscience Methods 196 (2011) 51-59} for best results.

KL et al 2012. <br><br>IR or fluorescent detection systems not yet tested, they but are expected to work well with higher primary antibody dilutions because of the increased sensitivity of the detection methods.<br><br>Suggested dilutions for IHC are 1:50-1:1,000. Fresh frozen, 4% paraformaldehyde fixed frozen, or formalin fixed paraffin embedded tissues are all suitable. Optimal dilutions must be determined by the end user. Antigen retrieval is required in fixed tissues for optimal staining.<br><br>Antibody was tested on 4% paraformaldehyde/0.1% glutaraldehyde fixed frozen tissue from 3xTg and 5xFAD mice. MOAB-2 antibody detects intraneuronal and extracellular beta-amyloid in IHC and does not detect APP {Youmans KL et al 2012}.<br><br> The antibody also reacts with archival formalin-fixed, paraffin-embedded tissue samples with antigen Heat Induced Epitope Retrieval (HIER): Recommended Citrate, pH 6.0 buffer for HIER. Signal was weak without antigen retrieval. Immunoreactively was expressed in intraneural-amyloid deposition (plaque) in Alzheimer's brain. MoAB-2 was found to be extremely clean and with an excellent signal to noise ratio with no neuro-cellular diffusive staining.<br><br>In addition MOAB-2 demonstrated no significant differences in A-beta detection using paraffin fixed, free-floating sections {Youmans KL et al 2012}. Formic acid (FA) treatment resulted in optimal detection of both intraneuronal and extracellular A-beta compared to without FA (incubated in 88% FA 8 min, Youmans KL et al 2012). Free floating tissue sections were permeabilized in TBS containing 0.25% Triton X-100 (TBSX; 3 x 10 min), blocked with 3% horse serum in TBSX (3 x 10 min) followed by 1% horse serum in TBSX (2 x10 min) and incubated with appropriate primary antibodies diluted in TBSX containing 1% horse serum overnight. See Youmans KL et al 2012 for full IH(P) protocol and method details.<br><br> For IF, suggested dilution is 1:100-1:500. The antibody was tested on 4% PFA fixed frozen tissue. Fixed tissues were washed in TBS (3 x 10 min), then incubated in 88% FA (8 min), and then permeabilized in TBSX (3 x 10 min), and blocked in TBSX containing 5% bovine serum albumin (BSA; 1 hr). Sections were subsequently incubated with appropriate primary antibodies diluted in TBSX containing 2% BSA overnight on an oscillatory rotator. Detection was via fluorescently labelled absorbed secondary antibodies {Youmans KL et al 2012}.<br><br>For IP, the suggested dilution is 1:200 to 1:1,000 for labeled beta-amyloid using Protein A/G conjugated beads as the capture vehicle {Youmans KL et al 2012}.<br><br>In an ELISA, a dilution of 1:50-1:1000 is suggested. The antibody has been tested in ELISAs on synthetic beta-amyloid and tissue homogenates from beta-amyloid-Tg mice.

Specificity:
MOAB-2 detects preparations enriched in U-, O-, F-A?42, and U-A?40 by dot-blot, and is thus a pan-specific A? antibody. However, MOAB-2 is selective for the more neurotoxic A?42 compared to A?40. Indeed, MOAB-2 demonstrated a titration against antigen concentration, and detects A?40 at 2.5 pmol but U-, O- and FA?b42 at antigen concentrations as low as ~ 0.1 pmol {Youmans. KL et al 2012}. MOAB-2 does not detect APP (Amyloid precursor protein). Human, Rat, other species not yet tested.By Dot blot, MOAB-2 detected rat A?40 and human A?40, albeit with less affinity than for A?42. {Youmans. KL et al 2012}
Storage:
After reconstitution keep aliquots at -20 ° to -70°C for a higher stability. At 2-8°C keep up to one week, insulated, protected from light; use sterile methods and pipettes. Highly purified glycerol (1:1) may be added for an additional stability. Avoid repetitive freeze/thaw cycles. Keep tightly closed when not in use and protected from light.

Mouse anti-Microtubule Associated Protein 2 (MAP2) Monoclonal Antibody (Unconjugated), suitable for WB, IHC-Frozen, ICC.
Background Info:
Microtubules are 25nm diameter protein rods found in most kinds of eukaryotic cells. They are polymerized from a dimeric subunit made of one 'a' subunit and one 'b' tubulin subunit. Microtubules are associated with a family of proteins called microtubule associated proteins (MAPs), which includes the protein t (tau) and a group of proteins referred to as MAP1, MAP2, MAP3, MAP4 and MAP5. MAP2 is made up of two ~280 kDa apparent molecular weight bands referred to as MAP2 a and MAP2 b. A third lower molecular weight form, usually called MAP2c, corresponds to a pair of protein bands running at ~70 kDa on SDS-PAGE gels. All these MAP2 forms are derived from a single gene by alternate transcription, and all share a C-terminal sequence which includes either three or four microtubule binding peptide sequences, which are very similar to those found in the related microtubule binding protein t (tau). MAP2 isoforms are expressed only in neuronal cells and specifically in the perikarya and dendrites of these cells. Antibodies to MAP2 are therefore excellent markers on neuronal cells, their perikarya and neuronal dendrites.
