Figure 3: Effects of penetration of lactophoricin-I (N-23-T) into DPPC and DPPG monolayers on surface pressure and electric surface potential ( ); the and the values calculated as difference in the and the ordinate of the isotherms registered on lactophoricin-I (N-23-T) solution (1 μM) and the pure water subphase (cf. Figures 1(a) and 1(b))—at identical cross-sectional areas ( ) per the phospholipid molecule, are plotted as a function of surface pressure of the pure phospholipid monolayer, .
