Figure 3. Biological activity of LukS-PV and corresponding mutants: rise of cytoplasmic calcium concentration due to human neutrophil activation.

Figure 3

Values represent the calcium entry slope expressed in percent of maximum calcium fluorescence (after neutrophil lysis with Triton X-100 0.05% v/v) per second. Statistical analysis: ns, non-significant; *, p<0.05; **, p<0.01; ***, p<0.001 (one-way ANOVA with Dunnett's post test, n = 6).
