Tumor-Associated Glycoprotein 72 (TAG-72) is an oncofetal mucin antigen expressed by normal secretory endometrium and most human adenocarcinomas, including colorectal, gastric, pancreatic, mammary, and ovarian. Antibody B72.3 recognizes a carbohydrate epitope identified as sialylated Tn antigen. This antigen is expressed by invasive ductal breast carcinomas, colon, esophageal, lung and endometrial adenocarcinomas. It is not expressed by leukemias, lymphomas, sarcomas, mesotheliomas, melanomas, benign tumors, or non-endometrial normal tissues. TAG-72 expression in fetal tissue is only observed in tissues of the gastrointestinal tract, including the colon, esophagus and stomach.
