Description
Introduction: CA19-9 Cancer Antigen, aka CA19-9, is a cell surface glycoprotein complex most commonly associated with pancreatic ductal adenocarcinoma. The immunohistologic distribution of CA19-9 in tissues is consistent with the quantitative determination of higher CA19-9 concentrations in cancer than in normal or inflamed tissues. CA19-9 Cancer Antigen is a tumour marker raised in blood of patients with carcinoma of the gastro-intestinal tract. A declining Cancer Antigen CA19-9 value may be indicative of a favorable prognosis and good response to treatment.
Description: The Human CA19-9 Cancer Antigen is having a molecular mass of approximately 210kDa and was purified from human carcinoma cell line
