Hemolytic activity of lipopeptides.

(A) The indicated concentration of SLPs were added to a 1% porcine RBC suspension in PBS, followed by incubation for 1 h at 37 °C and centrifugation. Pictures were taken after collecting a portion of the supernatant for quantification of hemolysis. (B) Hemolytic curve. Hemolysis (measured at OD540) is shown as a function of SLP concentration. 100% represents the OD obtained using 0.1% Triton X-100-treated red blood cells.
