TY - JOUR TI - Synergistic cytotoxic effects of antibodies directed against different cell surface determinants AB - Three antibody populations were raised in rabbits against surface antigens on guinea-pig L/sub 2/C leukaemic lymphocytes: against idiotypic determinants on the lambda chain of the surface immunoglobulin, against C region determinants on the lambda chain, and against the surface antigens recognised by conventional anti-lymphocyte sera. Complement and K-cell cytotoxicities effected by the antibodies on L/sub 2/C cells were studied in vitro. In both cytotoxic systems mixtures of the antibodies revealed synergy, in that the titres of the mixtures exceeded predicted additive titres of their components. The synergy was greater when the mixed antibodies were directed to determinants on the same molecule rather than to determinants on different molecules.
