Representative compression isotherms (from three replicates) for (A) DMPC (B) DPPC and (C) DSPC in the presence of increasing concentrations of PFBS. The compression isotherms were obtained at 37 °C on a subphase consisting of 150 mM NaCl and 1.5 mM CaCl2, with a compression rate of 10 mm/min (7.5 cm2/min). PCs were added as a solution in 9: 1 (v: v) hexanes: ethanol, which was allowed to evaporate before compression. The LE-to-LC transition for DPPC is shown with an arrow. Control isotherms were obtained by addition of blank solvent to PFBS-containing subphases followed by compression. Only the control for the 10 mM PFBS subphase, which gave the highest surface pressure change upon compression, is shown on each graph.
