Carcinoembryonic Antigen（CEA）

Recombinant human carcinoembryonic antigen (CEA) CEACAM5, also known as CEA or CD66e, belongs to the large CEACMA subfamily of the immunoglobulin superfamily. CEACAM5 is mainly expressed by epithelial cells and is a glycoprotein with a molecular weight of 180kDa and containing 60% carbohydrates. The N-terminus of CEACAM5 contains an immunoglobulin V-type domain, followed by 6 immunoglobulin C2-type domains and a glycosylphosphatidylinositol anchor (also called a dot). exists as a source dimer. CEACAM5 and CEACAM6 are overexpressed in many tumor tissues, and they are related to tissue adhesion and invasion. It functions as a homotypic intercellular adhesion molecule and is a widely used tumor marker because it has higher expression levels in tumor tissues than in corresponding normal tissues.
