Description: Epithelial antigen is a cell surface glycoprotein and is broadly distributed in epithelial cells and displays a highly conserved expression in carcinomas. Epithelial antigen has been shown to play an important role as a tumor cell marker in lymph nodes from patients with esophageal carcinoma. Epithelial antigen can be used to distinguish between basal cell and basosquamous carcinomas and squamous cell carcinoma of the skin.

Catalog Number: (CA76634-516)

Supplier: Diagnostic Biosystems

Description: Galectin-3 is a member of the beta-galactoside-binding protein family that plays an important role in cell adhesion, cell matrix interactions, macrophage activation, angiogenesis, metastasis, and apoptosis.

Galectin-3 shows strong diffuse cytoplasmic staining in most cases of papillary thyroid carcinoma (PTC), most poorly differentiated thyroid cancers demonstrate galectin-3 protein expression while it is not expressed in anaplastic thyroid cancers. (1) Upregulated expression of galectin-3 is involved in cancer progression and metastasis, and it is suggested that Galectin-3 may be a valuable tool to support diagnosis of parathyroid carcinoma. (2)

Galectin-3 has also been reported to play important roles in the progression of prostate cancer, and their heterogeneous expressions might be associated with different cancer subtypes. (3)

Description: This antibody is specific to a 38 kDa protein. Synaptophysin is an glycoprotein occurring in presynaptic vesicles of neurons in the brain, spinal cord, retina, vesicles of adrenal medulla and in neuromuscular junctions. This antibody reacts with neuroendocrine neoplasms of neural as well as epithelial types.

Catalog Number: (CA76634-552)

Supplier: Diagnostic Biosystems

Description: This antibody stains the cytoplasm of antigen-positive liver cells in patients with Type B viral hepatitis. This antibody reacts with the 'a' determinant present on the HBsAg subtypes ayw1, ayw2, ayw3, ayw4, ayr, adw2, adw4 and adr. It does not react with normal tissues.

Supplier: Diagnostic Biosystems

Description: The mammaglobin gene was first identified using a differential screening approach directed at the isolation of novel, human breast cancer-associated genes. Mammaglobin-A is highly overexpressed in breast cancer cell lines and primary breast tumors. This pattern of expression is restricted to mammary epithelium and metastatic breast tumors. Thus, mammaglobin-A-specific T cell immune responses may provide an important approach for the design of breast cancer-specific immunotherapy.

Supplier: Diagnostic Biosystems

Description: Myeloperoxidase metabolizes most of the hydrogen peroxide generated by activated phagocytes. This antibody stains strongly with the cytoplasm of myeloid cells. The antibody detects myeloperoxidase found in myeloid cells of acute myeloid leukemia. The myeloperoxidase gene has been localized to chromosome 17.

Catalog Number: (CA76634-880)

Supplier: Diagnostic Biosystems

Description: p63 is a homolog of the tumor suppressor p53, it is identified in basal cells in the epithelial layers of a variety of tissues, including epidermis, cervix, urothelium, breast and prostate. p63, vital for the development of the prostate and selectively expressed by normal prostate basal cells, has been shown to be a promising complementary basal cell specific marker to High Molecular Weight-Cytokeratin (HMW-CK), for the differential diagnosis of benign prostatic lesions and prostatic carcinoma. p63 has also been shown to be a sensitive marker for lung squamous cell carcinomas (SqCC), with a sensitivity of ~90% . Specificity for lung SqCC, vs. lung adenocarcinoma (LADC), is approximately 80. In breast tissue, p63 has been identified in myoepithelial cells of normal ducts.

Catalog Number: (CA76634-650)

Supplier: Diagnostic Biosystems

Description: This antibody reacts with a 32 kDa protein. Granzymes are neutral serine proteases, which are stored in specialized lytic granules of cytotoxic T lymphocytes (CTL) and in natural killer (NK) cells. A number of granzymes (A to G) have been isolated and cloned. Human granzyme B is involved in target cell apoptosis during lymphocyte-mediated cytotoxicity. This antibody is useful in the localization of granzyme B containing lytic granules and for the characterization of activated CTL or NK cells.

Catalog Number: (CA76634-654)

Supplier: Diagnostic Biosystems

Description: This antibody reacts with a 160 kDa (unreacted dimer) and 80 kDa (reduced monomer) protein. Factor XIII is a β-globulin found in plasma and is composed of two subunits, Factor XIII-A and Factor XIII-B. Factor XIII-A is the catalytic subunit and is a dimer of M.W. 160 kDa. Factor XIII is a dermal dendrocyte marker and shows variable reaction with these types of tumors. Factor XIII can be used for histiocytic phenotyping and has been reported to mark capillary hemangiomas and tumors of the central nervous system.

Catalog Number: (CA76634-886)

Supplier: Diagnostic Biosystems

Description: ROS1 rearrangements occur infrequently in lung ACA, however given the frequency of lung cancer in the population, ROS1-rearranged tumors represent a significant number of cancer patients. ROS1 gene rearrangements are reported in 1 to 2% of lung adenocarcinomas (ACA) and are associated with response to the multitargeted tyrosine kinase inhibitor, crizotinib. ROS IHC can be readily incorporated into the diagnostic surgical pathology workup of lung adenocarcinoma, with results confirmed by FISH as needed.

Supplier: Diagnostic Biosystems

Description: This antibody reacts with the zymogen as well as the activated form of cathepsin D. It stains fibroblasts and macrophages strongly but stains weakly with the myoepithelial cells of breast. It stains the sweat ducts and glands in the skin, islets cells and granules of pancreatic acini.

Supplier: Diagnostic Biosystems

Description: Podoplanin is a 38 kDa membrane mucoprotein originally detected on the surface of rat podocytes .The antibody against podoplanin (D2-40) reacts to a 40 kDA sialogylcoprotein found on lymphatic endothelium, fetal testis, and on the surface of testicular germ cell tumors. Podoplanin can be used to assist pathologists in identifying lymphatic endothelium to determine lymphatic invasion and also can be used to help differentiate mesothelioma from adenocarcinoma.
