NCI: A recombinant counterpart of tumor-associated KSA antigen (Ep-CAM), a type-I transmembrane glycoprotein cellular adhesion molecule with a molecular mass of 40 kDa, overexpressed on the majority of tumor cells of most human epithelia in a of variety of tumor tissues such as stomach, colon, pancreas, gall bladder, bile duct, mammary gland, breast, and lung carcinoma. It has been suggested to be involved in the differentiation, growth, and organization of epithelial cells within tissues under normal physiological conditions. The antigen has been used as a target for diagnosis and for passive and active immunotherapy of colorectal cancer. Immunization with KSA Glycoprotein elicits both humoral and Th1-associated cellular immune responses.
