The molecular weight of CA19-9 of the patients with pancreas carcinoma was ~2000kD, however those of the patients with liver disorder and diabetes mellitus were showed 2000kD and round 700kD. The assay for Pancreatic and Gastro-Intestinal Cancer marker (PC-199) measures a carbohydrate antigenic determinant expressed on a high molecular weight mucin. This mucin type of glycoprotein is found in the area of pancreatic and colon and hepatocellular carcinomas.
