CEA Antibody

Carcinoembryonic antigen (CEA) is a complex immunoreactive glycoprotein with a molecular weight of 180,000 comprising 60% carbohydrate. CEA is found in adenocarcinomas of endodermally derived digestive system epithelia and in fetal colon. CEA immunoassay is useful in the diagnosis and serial monitoring of cancer patients for recurrent disease or response to therapy, particularly in the case of colon cancer.
