FRET interaction of NBD-PE and Rh-PE in model lipid vesicles. Degree of FRET interaction was calculated as stated in Materials and Methods for vesicles composed of model lipids. Measurements were done at 23°C (A) and 37°C (B). These data represent the mean ± S.E.M. for three determinations, where significant differences from 100% POPC (Model 1) vesicles are represented by *P ≤ 0.05; **P ≤ 0.01.
