The peptide-induced lipid vesicle leakage was determined using a fluorescence-based assay as described previously in detail (Grau-Campistany et al., 2015). Leakage of ANTS/DPX from DMoPC/DMoPG (1:1), POPC/POPG (1:1), DErPC/DErPG (1:1), or POPE/POPG (1:1) vesicles was determined at a range of peptide concentration. Vesicle solution was added to a peptide solution in buffer at pH = 7.5, and the fluorescence signal was followed for 10 minutes. The data was scaled to the signal after addition of Triton-X, which gave the value for 100% leakage. Measurements were repeated at least three times.
