Anti-MS4A1 Mouse Monoclonal Antibody [clone: B9E9]
Supplier: ProSci Inc.
This antibody recognises a protein of 33-37 kDa, identified as CD20 (Workshop V; Code CD20.12). The antibody recognises the extracellular domain of CD20. The epitope is similar to or identical to that recognized by other CD20 antibodies including Leu-16 and B1. This antibody can be used for immunophenotyping of leukemia and malignant cells, B lymphocyte detection in peripheral blood, Bcell localization in tissues and B lymphocyte purification by immunosorbent methods. CD20 is a non-Ig differentiation antigen of Bcells and its expression is restricted to normal and neoplastic Bcells, being absent from all other leukocytes and tissues. It is expressed by pre Bcells and persists during all stages of Bcell maturation but is lost upon terminal differentiation into plasma cells. Protein passes through the membrane 4 times with both ends in cytoplasm and exposes one short and one longer loop to the external environment. CD20 is not glycosylated in resting Bcells and its cytoplasmic domains are differentially phosphorylated upon activation. It acts as a calcium channel involved in Bcell activation and cell cycle progression.

Anti-POMC Mouse Monoclonal Antibody [clone: CLIP/1407]
Supplier: ProSci Inc.
ACTH (or Corticotropin) is a 39 amino acid active peptide produced by the anterior pituitary. This mAb is specific to CLIP (aa 25-39) and does not react with Synacthen (aa 1-24). POMC (pro-opiomelanocortin or corticotropin-lipotropin) is a 267 amino acid polypeptide hormone precursor that goes through extensive, tissue-specific posttranslational processing by convertases. POMC is cleaved into ten hormone chains named NPP, ACTH, alpha-MSH (Melanocyte Stimulating Hormone), beta-MSH, gamma-MSH, CLIP (corticotropin-like intermediary peptide), Lipotropin-beta, Lipotropin-gamma, beta-endorphin and Met-enkephalin. ACTH is also produced by cells of immune system (T-cells, B-cells, and macrophages) in response to stimuli associated with stress. Anti-ACTH is a useful marker in classification of pituitary tumors and the study of pituitary disease. It reacts with ACTH-producing cells (corticotrophs). It also may react with other tumors (e.g. some small cell carcinomas of the lung) causing paraneoplastic syndromes by secreting ACTH.

Anti-ESR2 Mouse Monoclonal Antibody [clone: NR3Gb-1]
Supplier: ProSci Inc.
Estrogen receptors (ER) are members of the steroid/thyroid hormone receptor superfamily of ligand-activated transcription factors. Estrogen receptors, including alpha and beta, contain DNA binding and ligand binding domains and are critically involved in regulating the normal function of reproductive tissues. They are located in the nucleus, though some estrogen receptors associate with the cell surface membrane and can be rapidly activated by exposure of cells to estrogen. ER alpha and beta are differentially activated by various ligands. Ligand interaction triggers a cascade of events, including dissociation from heat shock proteins, recepter dimerization, phosphorylation and the association of the hormone activated receptor with specific regulatory elements in target genes. Evidence suggests that ER alpha and beta may be regulated by distinct mechanisms even though they share many functional characteristics.

Anti-CD5 Mouse Monoclonal Antibody [clone: C5/473]
Supplier: ProSci Inc.
This antibody recognises a 67 kDa transmembrane protein, which is identified as CD5. The CD5 antigen is found on 95% of thymocytes and 72% of peripheral blood lymphocytes. In lymph nodes, the main reactivity is observed in T cell areas. antibody to CD5 is a pan T-cell marker that also reacts with a range of neoplastic B-cells, e.g. chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), mantle cell lymphoma, and a subset (~10%) of diffuse large B-cell lymphoma. CD5 aberrant expression is useful in making a diagnosis of mature T-cell neoplasms. CD5 antibody detection is diagnostic in CLL/SLL within a panel of other B-cell markers, especially one that includes anti-CD23. CD5 antibody is also very useful in differentiating among mature small lymphoid cell malignancies. In addition, antibody to CD5 can be used in distinguishing thymic carcinoma (+) from thymoma (-).

Anti-CEACAM5 Mouse Monoclonal Antibody [clone: C66/1009]
Supplier: ProSci Inc.
This antibody recognises proteins of 80-200 kDa, identified as different members of the CEA (Carcinoembryonic Antigen) family. CEA is synthesised during development in the fetal gut and is re-expressed in increased amounts in intestinal carcinomas and several other tumors. This antibody does not react with nonspecific cross-reacting antigen (NCA) and with human polymorphonuclear leucocytes. The antibody shows no reaction with a variety of normal tissues and is suitable for staining of formalin/paraffin tissues. CEA is not found in benign glands, stroma, or malignant prostatic cells. antibody to CEA is useful in detecting early foci of gastric carcinoma and in distinguishing pulmonary adenocarcinomas (60-70% are CEA+) from pleural mesotheliomas (rarely or weakly CEA+). CEA antibody positivity is seen in adenocarcinomas from the lung, colon, stomach, esophagus, pancreas, gallbadder, urachus, salivary gland, ovary, and endocervix.

Anti-TG Mouse Monoclonal Antibody [clone: 6E1 or TGB05]
Supplier: ProSci Inc.
Thyroglobulin is a 660 kDa dimeric pre-protein with mutiple glycosylation sites, detected at ~300 kDa in western blot. It is produced by and processed within the thyroid gland to produce the hormone thyroxine and triiodothyronine. Prior to forming dimers, thyroglobulin monomers undergo conformational maturation in the endoplasmic reticulation. The vast majority of follicular carcinomas of the thyroid will give positive immunoreactivity for thyroglobulin antibody even though sometimes only focally. Poorly differentiated carcinomas of the thyroid are frequently thyroglobulin antibody negative. Adenocarcinomas of other-than-thyroid origin do not react with this antibody. This antibody is useful in identification of thyroid carcinoma of the papillary and follicular types. Presence of thyroglobulin in metastatic lesions establishes the thyroid origin of tumor. Thyroglobulin antibody, combined with calcitonin antibody, can identify medullary carcinomas of the thyroid. Furthermore, thyroglobulin antibody, combined with TTF1 antibody, can be a reliable marker to differentiate between primary thyroid and lung neoplasms.

Anti-MUC1 Mouse Monoclonal Antibody [clone: MUC1/955]
Supplier: ProSci Inc.
Mucin-1 is a large cell surface mucin glycoprotein expressed by most glandular and ductal epithelial cells and some hematopoietic cell lineages. It is expressed on most secretory epithelium, including mammary gland and some hematopoietic cells. It is expressed abundantly in lactating mammary glands and over expressed in >90% breast carcinomas and metastases. The transgenic protein has been shown to associate with all four c-erbB receptors and localize with c-erbB1 (EGFR) in lactating glands. The gene contains seven exons and produces several different alternatively spliced variants. The major expressed form of the protein uses all seven exons and is a type 1 transmembrane protein with a large extracellular tandem repeat domain. The tandem repeat domain is highly O glycosylated and alterations in glycosylation have been shown in epithelial cancer cells. Mucin-1 antibody is useful as a pan-epithelial marker for detecting early metastatic loci of carcinoma in bone marrow or liver. The specific epitope of this Mucin-1 antibody has not yet been determined.

Anti-TFF1 Mouse Monoclonal Antibody [clone: GE2]
Supplier: ProSci Inc.
This antibody recognises a polypeptide of ~6.5 kDa, identified as Estrogen Inducible Protein pS2. The antibody's epitope is localized between amino acids 57-84. pS2 is a trefoil peptide. Trefoil peptides are protease resistant molecules secreted throughout the gut that play a role in mucosal healing. These peptides contain three intrachain disulfide bonds, forming the trefoil motif, or P-domain. Estrogen Inducible Protein pS2 is known to form dimers and this dimerization is thought to play a role in its protective and healing properties. About 60% of breast carcinomas are positive for estrogen inducible protein pS2. Staining is cytoplasmic, often with localization to the Golgi apparatus. It is shown to be localized in normal stomach mucosa, gastric fluid, goblet cells in the colon and small intestine, and in ulcerations of the gastrointestinal tract. Several studies have shown that estrogen inducible protein pS2 is primarily expressed in estrogen receptor-positive breast tumors and it may define a subset of estrogen-dependent tumors that displays an increased likelihood of response to endocrine therapy.
