FIGURE 12.

Fractional release of calcein from SUVs of DPPG/DPPC (1:1) 1 min after the addition of (KIAGKIA)₃-NH₂ in the presence (open symbols) and in the absence (solid symbols) of 2.5 mol % F-lipid as a function of total (bound + free) peptide concentration. The lipid concentrations were 83 μM (♦), 166 μM (▴), 174 μM (▵), 332 μM (•), and 348 μM (○). The fluorinated lipid vesicles (open symbols) were indistinguishable from the nonfluorinated ones (solid symbols). Leakage is normalized with respect to that observed after treatment with 200 μL Triton X-100.
