BD, 567937, Biotin Mouse Anti-Human CD326 (EpCAM) 9C4

The 9C4 monoclonal antibody specifically binds to human epithelial cell adhesion molecule (EpCAM), also known as adenocarcinoma associated antigen and CD326. EpCAM is an approximately 40-kDa type 1 transmembrane glycoprotein and adhesion molecule that mediates intercellular interactions via homotypic adhesion. The epithelial cells present in non-squamous epithelia and tumors derived from such cells show EpCAM expression. Tumors arising from non-epithelial cells, such as lymphoma, mesothelioma, neuroblastoma, and melanoma, do not express EpCAM. The normal epithelial cells reactive with anti-EpCAM antibodies are those present in the (lower) respiratory tract; the (lower) gastrointestinal tract; tubules in the kidney; the surface epithelium of the ovary; the exocrine and endocrine pancreas; secondary germ cells of telogenic hair follicles; and secretory tubules of sweat glands in the skin, whereas the epidermis is negative. In addition, all epithelial cells in the thyroid and epithelial cells in the thymus show EpCAM expression, while the outer cortex and Hassall's corpuscles have low expression. EpCAM is expressed on a variety of stem and progenitor cells, and its down-regulation is associated with decreased proliferation and differentiation toward endoderm and mesoderm lineages.

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed.
1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
3. An isotype control should be used at the same concentration as the antibody of interest.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
