Fig 4. Cell permeabilizing activities of CTI and CTII on lipid bilayers.

Fig 4

1H-NMR spectra derived from the N+(CH3)3 groups of PC in large unilamellar liposomes composed of PC+ 10 mol% CL (A and B) or in PC+ 10 mol% PS (C and D) in the presence of potassium ferricyanide at 18°C and in the presence of CTII (A and C, top spectra) or of CTI (B and D, top spectra) at a cytotoxin/lipid molar ratio of 0.02. This figure shows a representative 1H-NMR traces from three independent experiments that showed similar results. Each sample (A-D) was measured in triplicate.
