Abstract

Bispecific monoclonal antibodies can be used to redirect peripheral blood lymphocytes against tumor cells. In the present study, a murine bispecific monoclonal antibody was developed using somatic hybridization. The antibody has two different binding arms: one arm directed against human CD3 receptor expressed on T-lymphocytes and the other against tumor associated glycoprotein TAG-72, expressed on human carcinomas, such as colon, breast, and pancreas. Partially purified antibody was capable of inducing human T- cell proliferation and preventing growth of colon cancer cell line in nu/nu mice in a tumor neutralization assay.
