Cholesterol accumulation increased by U18666A treatment.
By ASHUTOSH SINGHAL on 01/05/2018
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: HeLa
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.
