Cholesterol Detection Kit (cell-based)

Cholesterol is an essential structural component of animal cell membranes. It is required to maintain membrane structural integrity and fluidity. Cholesterol also serves as a precursor for the biosynthesis of several hormones, bile acid and vitamin D. Plasma membrane contains majority of the cellular cholesterol (80-90%) whereas little cholesterol resides in endoplasmic reticulum and in mitochondrial membrane. Transport of intracellular cholesterol within the cells to different compartments is through vesicular and non-vesicular pathways. Defects in these transport processes can alter cellular cholesterol metabolism resulting in pathological conditions. Filipin III is widely used as a probe for sterol localization in membranes. Interaction with cholesterol alters Filipin absorption and fluorescence spectra. This assay provides a simple, easy to perform, histochemical method of identification of unesterified cholesterol.

Figure 1: Liver cells (HepG2) cholesterol staining: HepG2 cells were cultured overnight and next day treated with U-18666A (1.25 uM) or vehicle control (DMSO) for 48 hrs. (a) Cells treated with DMSO alone demonstrated majority of the cholesterol is localized in Plasma membrane. (b) Treatment with U-18666A for 48 hrs resulted in intracellular accumulation of cholesterol. (c) Higher magnification of image B. Images were taken using Nikon TiE microscope.
