Quantification of adipocyte free and esterified cholesterol using liquid gel chromatography
BR Krause and AD Hartman
A reliable method for the separation of free and esterified cholesterol in
adipocyte extracts is described. The procedure uses Sephadex LH-20, a
lipophilic dextran gel, with a solvent system of chloroform-hexane 55:45
(v/v). Interference by excess triglyceride, such as that encountered in
adipocyte total lipid extracts, was not observed, and overall recovery of
both sterols exceeded 98%.
