Used in research and diagnostic applications to detect the tumor-associated glycoprotein 72 (TAG-72), a biomarker overexpressed in various cancers such as colorectal, ovarian, and pancreatic carcinomas. This antibody serves as a reference standard in immunoassays, flow cytometry, and immunohistochemistry to validate the performance of other anti-TAG-72 antibodies and to support the development of targeted cancer therapies. It is also employed in pharmacokinetic and biodistribution studies during the preclinical and clinical development of antibody-based therapeutics.
