Clone Host Grade Applications
Monoclonal Mouse Supernatant IH
Carbohydrate antigen 19-9 (CA 19-9) is a protein that exists on the surface of certain cells and is the most frequently used tumor markers in the clinical setting of cancer. It does not cause cancer; rather, it is a protein that is shed by the tumor cells, making it useful as a tumor marker to follow the course of the cancer. CA 19-9 is elevated in most patients with advanced pancreatic cancer, colorectal cancer, lung cancer, gall bladder cancer, gall stones, pancreatitis, cystic fibrosis, and liver disease. Very small amounts of CA 19-9 may also be found in healthy patients. Besides in patients with Lewis antigen blood group type, CA 19-9 is not elevated even in pancreatic cancers as they have a deficiency of fucosyltransferase needed to synthesize CA 19-9.
