INFLUENCE OF AVIDITY AND IDIOTOPE RECOGNITION ON THE MODULATION OF SURFACE-IMMUNOGLOBULIN ON MALIGNANT HUMAN B-CELLS BY RAT MONOCLONAL ANTIIDIOTYPE ANTIBODIES JOURNAL OF IMMUNOLOGY Campbell, M., Bieber, M., Levy, R., Teng, N. N. 1986; 136 (8): 2983-2988

Abstract

Immunoglobulin (Ig) was obtained from the tumor cells of patients with B cell malignancies by somatic cell hybridization to mouse-human heteromyeloma cells. The human Ig secreted by one of these hybridomas was used as an immunogen for the production of rat monoclonal antibodies (mAb). A panel of mAb specific for the idiotype (Id) was produced and characterized. Competitive binding studies that made use of [Se]-labeled anti-Id mAb (MAID) demonstrated several distinct yet topographically related Id on the Id-bearing Ig. These antibodies were shown to have avidities ranging from 0.38 to 45.3 X 10(8) l/mol. Additional studies demonstrated varying degrees of antigenic modulation of surface Id in vitro by MAID. The degree of modulation correlates with antibody avidity.
