Redirected lysis of P815 targets by RNK-16 clones expressing the 2B4 deletion mutants. Various transfected RNK-16 cell lines were used as effectors (indicated on x axis) at an effector-to-target ratio of 100:1 in a standard chromium release assay. As indicated, effectors were preincubated with control antibody (cAb) or with anti-2B4 as described for Fig. 2.
