TAG-72 may be expressed in a variety of adenocarcinomas including colorectal and ovarian adenocarcinomas. Monoclonal Antibody B72.3F(ab) is generally not immunoreactive with normal adult tissues, but may crossreact with normal salivary gland ducts, normal post-ovulatory endometria, some benign ovarian tumors, and fetal gastrointestinal tissues.
