CEA is frequently used as a differential marker for adenocarcinoma and mesothelioma. Carcinoembryonal Antigen (CEA) is a high molecular glycoprotein (180 kD), which is detected in foetal colon and in colorectal carcinoma. It is a component of the s. c. glycocalyx of the embryonal endodermal epithelium. In normal adult colon it is found in very small amount only. In colorectal carcinoma and metastases of intestinal carcinoma however, it is strongly exprimed. Human CEA.
