I used 2.5-10 ug/ml of U18666A to inhibit the cholesterol efflux in HeLa cells and it worked perfectly as I observed in U18666A treated HeLa cells accumulated cholesterol significantly. I used Filipin staining to image and quantitate the cholesterol levels.
I dissolved the U18666A in water and stored at -20C in aliquots.
