Ready-to-use ELISA kits are available for the detection of HEA125, an alias of the protein, epithelial cell adhesion molecule. The official gene symbol is EPCAM. The kits can detect several species variants of the protein, including: human, guinea pig, and other mammalian. The protein, with a mass of 34.9 kDa and length of 314 residues, is reported to be membrane-associated. It is a member of the EPCAM family and may be known by other names, including: trophoblast cell surface antigen 1, membrane component chromosome 4 surface marker (35kD glycoprotein), human epithelial glycoprotein-2, epithelial glycoprotein 314, cell surface glycoprotein Trop-1, and adenocarcinoma-associated antigen, and DIAR5.
