TAG-72 Products



Tumor-associated glycoprotein (TAG-72) is an oncofetal antigen with properties of a mucin. About 60% of carcinoma patients express TAG-72 in their sera. Majority of human adenocarcinomas including colorectal, pancreatic, gastric, ovarian, endometrial, mammary, and non-small cell lung cancer display some cell populations that are positive for Ab-1 staining. Weak or no reactivity has been observed with most cell types of normal adult tissue excepting the secretory endometrium. Ab-1 is reportedly useful in distinguishing pulmonary adenocarcinomas (B72.3+) from pleural mesotheliomas (B72.3-).
