Hemolysis and in vitro cytotoxicity assays.

<p>(A) Hemolytic activity. Fresh RBC suspension was incubated with peptides. The release of hemoglobin into the supernatant was monitored to determine membrane damage of RBCs. (B) <i>In vitro</i> cytotoxicity. Peptides were added to HaCaT keratinocytes, and cell viability was measured by the MTT assay after a 24-h incubation with the peptides. Data in (A) and (B) represent Data in (A) and (B) represent the mean±SD of 3 independent experiments.
