Flow cytometry evaluation of Ca2+ entry into human PMNs for different combinations of purified WT S and F proteins and their oxidized double mutants. (a) Oxidized LukS-PV mutants were tested with WT LukF-PV. (b) Oxidized LukF-PV double mutants were tested with WT LukS-PV. (c) Oxidized LukS-PV double mutants were tested with LukF-PV S8C-K20Cox. (d) Oxidized LukS-PV double mutants were tested with LukF-PV T5C-T21Cox.
