PRODUCT

Summary

Carbohydrate antigen 19-9 (CA 19-9), also known as sialyl-Lewis^A, is a tetrasaccharide with the sequence Neu5Acα2-3Galβ1-3[Fucα1-4]GlcNAcβ. It is used clinically to assist in the diagnosis of pancreatic cancer, but is more widely utilized to monitor therapy and detect recurrences in diagnosed cases. CA 19-9 is also elevated in many other diseases, including cholangiocarcinoma, colorectal cancer, hepatocellular carcinoma, and cirrhosis. GeneTex’s CA 19-9 mouse monoclonal antibody [GT933] demonstrates superior sensitivity for western blot, immunohistochemistry, and immunocytochemistry in comparative testing against other well-known CA 19-9 antibodies. Most significantly, glycan array interrogation using this antibody establishes that it is specific for sialyl-Lewis^A.
