BODIPY-Cholesterol is cholesterol tagged with a boron dipyrromethene difluoride (BODIPY) fluorophore used for monitoring sterol uptake and inter-organelle sterol flux in cells with excitation of 480 nm and emission of 508 nm.[1] The excretion of BODIPY cholesterol from late endoplasmic organelles depends on acidic lipase and Niemann pickc1 protein.[6]
In vitro, treatment with Bodipy-cholesterol in cells, prominent PM labeling is observed at 2–5 min; however, upon ≥30 min incubations, it is also observed the fluorescence labeling of intracellular structures.[2] In vitro efficacy test it suggested that accumulation of BODIPY-cholesterol in the media gave more reproducible values than assaying for the loss of the compound from the cells.[3] With 1 μg BODIPY-cholesterol analogs show a similar cellular localization in HeLa cells and exhibit similar cholesterol efflux properties from THP1 cells to HDL acceptors.[4] BODIPY-cholesterol efflux clearly increased when treatment of fibroblasts with the Hh pathway agonist SAG, which enhances Ptc protein expression, or over-expression of human Ptc in yeast.[5] Treatment with miR-758 inhibitor obviously increased ABCA1-dependent cholesterol efflux by BODIPY-Cholesterol efflux assay.[7] Micrographs of EPCs incubated with HDL labeld bodipy-cholesterol (50 µg/ml) 30 min, small cytoplasmic vesicles as well as large positive MVBs containing intraluminal microvesicles, tightly-packed with reaction products could be displayed. The internalized-HDL-derived bodipy-cholesterol was also spread within many of the stacked Golgi cisterns and the TGN.[8]
