General description

Biomolecules attached to BODIPY, is readily absorbed in the visible light. It results in greater fluorescence quantum yields. It is highly photostable and less sensitive to change in polarity and pH.


TOPFLUOR®Cholesterol is suitable:
  • for cholesterol-uptake assay
  • for BODIPY cholesterol labeling in live cell experiments
  • for the formation of giant Janus liposomes via poly(vinyl alcohol) (PVA)-assisted lipid swelling

Biochem/physiol Actions

BODIPY labelled cholesterol has similar properties to that of the naïve cholesterol. This serves as a cholesterol marker for live cells and aids in trafficking intracellular cholesterol. It might also help in indicating lipid storage diseases.

Cholesterol is an important membrane component, but our knowledge about its transport in cells is sparse. Previous imaging studies using dehydroergosterol (DHE), an intrinsically fluorescent sterol from yeast, have established that vesicular and non-vesicular transport modes contribute to sterol trafficking...

Analysis of sterol distribution and transport in living cells has been hampered by the lack of bright, photostable fluorescent sterol derivatives that closely resemble cholesterol. In this study, we employed atomistic simulations and experiments to characterize a cholesterol compound with...

Seminal plasma proteins of the fibronectin type II (Fn2) family modulate mammalian spermatogenesis by triggering the release of the lipids phosphatidylcholine and cholesterol from sperm cells. Whereas the specific interaction of these proteins with phosphatidylcholine is well-understood, their selectivity for...

Coupling atomic force microscopy (AFM) with high-resolution fluorescence microscopy is an attractive means of identifying membrane domains by both physical topography and fluorescence. We have used this approach to study the ability of a suite of fluorescent molecules to probe...
