Figure 2. Plots of successive small-angle X-ray scattering intensity profiles versus reciprocal spacing recorded of a fully hydrated dispersion of dipalmitoylphosphatidylcholine (a) and a codispersion of 10 mol% dolichol C95 in dipalmitoylphosphatidylcholine (b) recorded during a heating scan at 2°/min.

Figure 6. Small-angle X-ray scattering intensity patterns of mixed aqueous dispersions of SOPE containing 0; 1; 5 and 10 mol% dolichol C95 at three different temperatures. The profiles are plotted at the logarithm of intensity to emphasize the minor bands. Arrows indicate the 1/v3 and 1/v4 reflections from hexagonal-II phase.
