Cholesterol desorption from mixed cholesterol/phospholipid monolayers to βCyD in the subphase

Monolayer phospholipid	Desorption rate (pmol cm−2 min−1)
Pure cholesterol	39.2 ± 0.62
PSM	0.88 ± 0.16
DMPE	5.4 ± 0.32
PCPE	7.6 ± 0.49

Mixed monolayers containing 50 mol % of cholesterol were prepared at air/water interface at 22°C. The monolayers were compressed to 20 mN/m and maintained at a constant surface pressure. Cholesterol desorption to βCyD (1.7 mM) in the subphase was determined as a time function. The values are given as the average ± SD from at least three different monolayer experiments.
