Inhibition of PLY hemolytic activity by serum from different mouse strains.

<p>Shown are the average EC₅₀ values, SD and fold-change in EC₅₀ of PLY-mediated hemolysis of sheep RBCs after serial dilution into PBS containing 10% sera from the indicated mouse strains. The fold change = EC₅₀ in the presence of serum/EC₅₀ in PBS. Results from 3 independent experiments are shown. No PLY antibodies were detected in these sera (see <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1004353#ppat.1004353.s003" target="_blank">Table S1</a>). Note: Non-Swiss albino serum for <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1004353#ppat-1004353-t001" target="_blank">Table 1</a> was from a different pooled lot as that shown here.</p><p>Inhibition of PLY hemolytic activity by serum from different mouse strains.
