NK cytotoxicity correlations between peripheral blood mononuclear cells (PBMCs) and overnight cytokine-activated whole blood (WB) assays. Natural killer (NK) cytotoxicity assays were performed using PBMCs at an E:T ratio of (A) 40:1, (B) 20:1, and (C) 10:1 and 200 μL WB (n = 28 donors). Correlation between PBMCs and IL-2-, IL-2/IL-18-, IL-2/IL-21-, and IL-2/IL-18/IL-21-treated WB.
