EGP40 is a 40-43kDa transmembrane epithelial glycoprotein, also identified as epithelial specific antigen (ESA), or epithelial cellular adhesion molecule (Ep-CAM). It is expressed on baso-lateral cell surface in most simple epithelia and a vast majority of carcinomas. This antibody has been used to distinguish adenocarcinoma from pleural mesothelioma and hepatocellular carcinoma. This antibody is also useful in distinguishing serous carcinomas of the ovary from mesothelioma.

Titering of the EpCAM antibody may be required for optimal performance.

A human partial recombinant protein corresponding to amino acids 100-224 (extracellular domain) was used as the immunogen for the EpCAM antibody.

Store the EpCAM antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
