Adsorption of CLSE to a constant interfacial area. A Wilhelmy plate measured the γ at 37 °C after aspirating the surface of a subphase containing vesicles dispersed by sonication in HSC with a phospholipid concentration of 100 μM. A control experiment with 7 mM SDS at 23 °C shows the behavior expected for standard surfactants. (A) Individual replicates of the γ−time adsorption isotherms. The superimposed dashed lines give the smoothed fit to the experimental data that provided the basis for differentiation. (B) Instantaneous slopes of the adsorption isotherms, found by differentiating the smoothed curves, plotted against γ.
