Penetration of Milk-Derived Antimicrobial Peptides into Phospholipid Monolayers as Model Biomembranes

Figure 7

Effects of the stationary penetration of L-16-Y and N-23-T peptides into DPPG monolayer on (a) surface pressure ( ) and (b) electric surface potential ( ); the effects measured after 60 min. contacts are plotted as a function of density of the pure phospholipid monolayer characterized by the initial surface pressure, . The error bar for and is ±0.5 mN m−1, and for is ±20 mV, at maximum. The peptides’ concentration is 1 μM.
