FIG. 2.
Lytic activity of cultured PBMC in the presence of IL-2 assayed for LAK activity against Daudi targets (A) and for NK activity against K562 targets (B) measured from cytotoxicity assays. Lytic activity from 51Cr released into cell culture supernatants was measured with the microplate readers Microbeta Trilux and TopCount and by traditional gamma counting (LKB). Microbeta Trilux readings were done in the presence of solid (Lumalux) and liquid (Trilux) scintillation cocktails. CTL responses are means from seven experiments.
