1 General Introduction Tumor markers refer to the antigens and bioactive substances produced by the abnormal expression of oncogenes and their products in tumor tissues and cells. These antigenic substances are estimated to be produced in the places where the cells become malignant due to the inactivation of glycosyltransferases Or the activation of some embryos during the cell surface carbohydrates caused by changes in carbohydrate. Ca242 is a sialylated carbohydrate antigen that can be expressed in colon cancer cell lines
