Monitoring of cholesterol oxidation in a lipid bilayer membrane using streptolysin O as a sensing and signal transduction element

[Display omitted] •A fluorometric method for monitoring chol oxidation in a lipid bilayer is described based on the pore forming ability of SLO.•The 3β-OH configuration of sterol in lipid bilayers is important for SLO to form a nanopore.•The P30min value decreased almost linearly with the mole fract...
