title: Monoclonal antibodies reacting with colorectal tumours.
abstract: 25 mouse monoclonal antibodies were screened for cell surface reactivity with colorectal tumours using the indirect immunoperoxidase method. Five antibodies of the IgG subclasses were selected. LICR-LON-M8 was raised against human milk fat globule membrane (HMFGM). The remaining four antibodies 48-1, 3-48-2, 77-1, and 8-30-3 were raised against human bladder metastases. M8, 77-1, and 8-30-3 which showed epithelial membrane antigen (EMA) - like reactivity exhibited greater selectivity for colorectal cancer compared with normal colon. M8 and 77-1 are being evaluated for immunoscintigraphy of colorectal carcinoma.
