Figure 4. Dependence of zeta potential of LPS preparations (A, LPS Re; B, LPS Ra) on different peptide/LPS molar ratios.
LF11 (○) and lauryl-LF11 (●) were titrated against LPS suspensions and the zeta potential was determined from the electrophoretic mobility analysed by laser-Doppler anemometry. Note the charge overcompensation for lauryl-LF11.
