Figure 1From: The Bacillus anthracis cholesterol-dependent cytolysin, Anthrolysin O, kills human neutrophils, monocytes and macrophagesRecombinant ALO lyses primary human neutrophils in a dose dependent manner. Percent viability of PMNs measured by trypan blue after 10 min incubation with various concentrations of rALO in serum free conditions. The means and standard deviations of two independent experiments, each performed in duplicate are shown (Spearman correlation is -0.842, p = 0.004).Back to article page
