Figure 2: Effects of expanding DPPC and DPPG monolayers by lactophoricin-I (N-23-T). The (%) denotes the relative increase of area per the phospholipid molecule due to the peptide’s penetration. It is evaluated (with the accuracy below 2%) by comparing the - isotherms presented in Figures 1(a) and 1(b) at the same and plotted as a function of the . The peptide’s concentration is 1 μM.
