    Abstract:
    Membrane cholesterol influences a large number of cellular processes and the dynamics of cholesterol exchange between membranes is an area of active study. However, analogs containing a fluorophore on the isooctyl side chain of cholesterol are commonly used without regard for the potential impact of the fluorophore on membrane structure. We investigated the capacity of 3-hexanoyl-7-nitrobenz-2-oxa-1,3-diazol-4-yl-cholesterol (3-NBD-cholesterol), which is labelled at the C3 position, to trace cholesterol dynamics in cellular systems. Transfer of 3-NBD-cholesterol from erythrocytes to lipoproteins replicated known properties of cholesterol. Labelled cells were also readily detected by flow-cytometry and microscopy. Using flow-cytometry it was also possible to follow the uptake of 3-NBD-cholesterol labelled extracellular vesicles. These data indicate that 3-NBD-cholesterol is a versatile cholesterol tracer in different cell models and extracellular vesicles.
