LL-37 protects host DNA against degradation by S. aureus nuclease. Quantification of DNA and its degradation using different DNA-intercalating dyes: PicoGreen (a, b, d), SYTOX Green (c) and ethidium bromide (e) in the presence or absence of 5 µM LL-37 ± 100 U/ml S. aureus nuclease (MN). All graphs represent the mean ± SEM of minimum 3 independent experiments. * p < 0.05, ** p < 0.005, *** p < 0.001 by t test.
