Descripción

Acciones bioquímicas o fisiológicas

Cell-permeant fluorescent tracer useful to study the distribution and dynamics of cholesterol.

22-NBD Cholesterol (22-NBD-Cho), a fluorescence-labeled cholesterol, is a lipid microenvironment-sensitive dye and localizes in the membrane’s interior. 22-NBD Cholesterol has proven useful for real-time imaging of HDL-mediated cholesterol uptake, efflux, and intracellular trafficking in living cells. 22-NBD-cholesterol′s fluorescence intensity is reported to enhance in response to phase changes of membrane lipids from rafts to non-raft fractions, and orient opposite to cholesterol in lipid bilayers. 22-NBD-Chol serves as a fluorescent substrate for cholesterol-converting oxidoreductases. λ ex/em ~ 470-490/500-600 nm (the fluorescence intensity and emission maximum depend on the medium’s polarity).
