FIGURE 6.

Arrhenius plots for diffusion coefficients of NBD-DMPE in multilayers with different compositions. Data are mean ± SD from 30 photobleaching experiments on each of three samples. Lines give best-fit linear regression to the data. Only points at temperatures above 41°C were fitted for DPPC. For CLSE, points above and below 35°C were adjusted separately, whereas the point at 11°C was ignored (see text). The arrow indicates the temperature (35°C) at which the two linear segments for CLSE intersect.
