the rosetting of sheep erythrocytes ( srbc ) coated with non-haemagglutinating monoclonal antibodies rather than conventional haemagglutinating antisera revealed readily detectable fcr on most splenic natural killer ( nk ) cells since 76 % of splenic lymphocytes forming conjugates with yac also rosetted with srbc coated with high concentrations of monoclonal anti-srbc antibody of the igg2b subclass and since ficoll depletion or enrichment of splenic lymphocytes rosetting with igg2b-coated srbc resulted in a corresponding 4-fold decrease or increase in conjugate-forming cells and a 10-fold decrease or increase in nk cytolytic activity .
