Of 14 monoclonal antibodies produced in six different laboratories, 13 bound to purified preparations of carcinoembryonic antigen (CEA). All antibodies reacted to spent medium of colorectal carcinoma cell lines. Competitive binding studies indicated that 12 different antigenic determinants representing six different groups were detected on the CEA molecule(s). Six antibodies were used in double determinant radioimmunoassays (RIA) to detect CEA and CEA-related antigens in sera of 311 patients with various gastrointestinal diseases and of normal donors. None of up to 115 sera of healthy donors had elevated antigen levels with four out of the six monoclonal antibodies tested, whereas up to 9% of sera showed elevated antigen levels when tested with two antibodies. Between 1.4% and 4.4% of sera from patients with inflammatory and benign neoplastic diseases of the gastrointestinal tract were positive. Antigen levels were elevated in 56 to 75% (depending on antibody used) of sera from patients with advanced gastrointestinal tumors. These preliminary results indicate that double-determinant immunoassays with a panel of monoclonal antibodies might improve conventional CEA assays by reducing the number of false positive sera detected by polyclonal sera in patients with benign inflammatory bowel diseases.
