Tumor Associated Glycoprotein (TAG-72) 0,5 mL
Specificity and Comments:
B72.3 recognizes an oncofetal antigen of >1,000kDa, identified as a tumor-associated glycoprotein (TAG-72) with properties of a mucin. 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 B72.3 staining. Weak or no reactivity has been observed with most cell types of normal adult tissue excepting the secretory endometrium. About 60% of carcinoma patients express TAG-72 in their sera. It is reportedly useful in distinguishing pulmonary adenocarcinomas that are B72.3 (+) from pleural mesotheliomas that are B72.3 (-).
