Inhibition of complement-mediated hemolysis by peptide P10. NHS was pre-incubated with various amounts (0, 5, 10, 20 μg) of peptide P10 and rTs-Pmy in Mg-EGTA solution (5 mM MgCl2, 10 mM EGTA) for 30 min before adding the mixture into freshly washed ER (1 × 108) in 100 μl HBSS at 37°C for 30 min. rTs 87 was used as a non-relevant control. The amount of hemoglobin released into the supernatant was measured at 412 nm, and the percent lysis was calculated compared to the complete lysis (water). The results are shown as the means ± SE for three independent experiments. *p < 0.05. **p < 0.01.
