Stemcell, 60146, Anti-Human CD326 (EpCAM) Antibody, Clone 323/A3

The 323/A3 antibody reacts with the human epithelial cell adhesion molecule (EpCAM or CD326), an ~40 kDa type I transmembrane glycoprotein which functions as a homophilic and Ca++-independent adhesion molecule. EpCAM has roles in several cellular processes, including signaling, migration, proliferation, and differentiation. It is expressed early during erythrogenesis and has been identified as a stem cell marker. The EpCAM protein is found on the basolateral membrane of most normal epithelial cells and is highly expressed in bone marrow, colon, and lung. EpCAM is not expressed on mesothelial cells or mesotheliomas, and so is widely used as a diagnostic marker to distinguish mesothelioma and carcinoma cells, as well as serving as a target for immunotherapeutic treatment of carcinomas.
