Biological Activity: Fluoresterol (22-NBD Cholesterol) is a cholesterol-specific fluorescent probe with cholesterol-mimicking binding properties. Fluoresterol is ineffective orally and does not cross the blood-brain barrier. Fluoresterol specifically binds to cholesterol transport-related proteins (such as ABCA1 and ABCG1) and is primarily used in cholesterol metabolism research, particularly for the visualization and quantitative analysis of cholesterol absorption, efflux, intracellular transport efficiency, and reverse cholesterol transport (RCT) processes. The commonly used concentration of Fluoresterol in in vitro experiments is 0.1-10 μM, and the commonly used dose in in vivo experiments is 5-20 mg/kg (gavage or intraperitoneal injection), with excitation/emission wavelengths of 472/540 nm. Fluoresterol can be applied to the study of cholesterol metabolism mechanisms related to hyperlipidemia, atherosclerosis, and non-alcoholic fatty liver disease (NAFLD)[1][2].
