Penetration of Milk-Derived Antimicrobial Peptides into Phospholipid Monolayers as Model Biomembranes
Figure 6
Effects of penetration of L-16-Y and N-23-T peptides to DPPC monolayer under stationary diffusion conditions on (a) surface pressure and (b) electric surface potential (); the and 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.
