Endo-NF treatment has no impact on NK cell cytotoxicity. (A) FACS analysis of PSA expression with and without Endo-NF treatment. (B) NK cells separated via CD56 were investigated in a 4 h-killing assay with and without Endo-NF treatment. Data shown are the average mean ± SEM from one out of three independent experiments. (C) Comparison of killing efficiencies at the target effector ratio 1:50 shows no difference of treated and untreated cells. Data shown are the average mean ± SEM from three independent experiments. Control refers to the killing efficiency of untreated NK cells. (D) Comparison of vitality with and without Endo-NF treatment shows no significant loss of vitality. Data shown are the average mean ± SEM from three independent experiments.
