Protection of CaSki cells from HSV-2 infection. Different peptides at 5, 10, 25, 50, and 100 μg/ml were incubated with the virus for 2 h and then added to CaSki cell monolayers. Plates were incubated at 37°C for 72 h, and cell viability was measured with a CCK-8 kit. Data are presented as means ± SD of three to five experiments at each concentration of individual peptide. Asterisks identify the peptide whose activity against HSV-2 differed significantly from that of HD5 at the indicated concentration (P < 0.05).
