A rapid and sensitive assay for determination of cholesterol in membrane lipid extracts

Abstract
A commercially available enzymatic assay (Boehringer Monotest) was modified to allow a rapid and sensitive determination of cholesterol in membrane lipid extracts. This was achieved by adding 0.5% Triton X-100 to the reagent solution. The detergent did not interfere with the assay. The relationship between the amount of cholesterol per assay and the absorbance at 500 nm was linear up to 100 micrograms. The recovery in the assay was better than 95%. The assay was applied to the determination of cholesterol in erythrocyte membrane lipid extracts.
