There are a number of ELISA Kits available for the measurement of GA733-2, another term for the human protein, epithelial cell adhesion molecule. Other synonyms may include: cell surface glycoprotein Trop-1, epithelial glycoprotein 314, human epithelial glycoprotein-2, membrane component chromosome 4 surface marker (35kD glycoprotein), and trophoblast cell surface antigen 1. It is encoded by the EPCAM gene to yield a protein 314 amino acids in length and 34.9 kDa in size. The protein is categorized into the EPCAM family. Versions of GA733-2 are present in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
