Figure 6. haNK cells have a higher killing frequency than healthy donor NK cells.

(A) Primary human NK cells purified from three independent healthy donors (HD) or haNK (10 Gy irradiated) cells were co-incubated with ¹¹¹In-labeled MDA-MB-231 (breast cancer) target cells at low E:T ratios for 18 h. (B) % specific lysis was used to calculate killing frequency by dividing the number of target cells killed by the number of effector cells used for the 0.625:1 ratio.
