Fig. 6.
Time derivative of the normalized area per molecule (d/dt(A/A0)) vs. time plots of Langmuir monolayers of PAPC, lysoPC–PAPC mixtures (A), and oxPAPC (B) at 37 °C and the bilayer equivalence pressure (30 mN/m). The initial rate of area decay increases with increasing concentration of lysoPC. After ~2000 s, the rate of area decay for all mixtures relaxes to the rate of pure PAPC. oxPAPC maintains a rate of normalized area decay greater than the rate of pure PAPC for greater than 18,000 s.
