Table 1. Size of membrane vesicles in different gradient fractions following cholesterol depletion with cyclodextrin.

The size distributions, as measured by dynamic light scattering, of control and cyclodextrin-treated membrane vesicles from different gradient fractions. Results are presented as the mean ± S.D. of triplicate determinations.

Treatment	Gradient fraction	Size (nm)
Control	Buoyant	779.5 ± 28.2
	Dense	453.0 ± 177.1
Cholesterol depletion	Buoyant	42.2 ± 11.5
	Dense	270.2 ± 68.8
