CA19-9 (Sialyl Lewisa)

CA19-9 is an antigen - dependent matrix on the structure of Sialated Lewis sugar.Sialated Lewis plays a role in cell adhesion as a functional ligand for inducing adhesion molecule e-selectin.Ca19-9 and CA50 (cancer-related mucocin antigen) are used as serological markers for the diagnosis of gastrointestinal and pancreatic cancers.It has been reported that the expression of ca19-9 and CA50 immunohistochemistry in pancreatic cancer is related to tumor differentiation, and strong staining has been observed in well-differentiated tumors.These two markers are also expressed in many benign lesions, such as chronic pancreatitis.
