oNK-1 cells harbor a high expression of activation markers. (A) NK activation markers were preferentially expressed in oNK-1 cells. A panel of NK activation and inhibitory markers in oNK-1 cells were profiled by flow cytometry. Three independent experiments of NK activation and inhibitory markers profiling were performed. The results were shown in mean ± standard deviation. The representative data were shown in Supplementary Fig. 2. (B) Both CD16 with low and high affinity at amino acid residue 176F and 176V were detected in oNK-1 cells. The characterization was analyzed by digital droplet PCR. NTC, no template control.
