Cholesterol/Cholesteryl Ester Kit II

Cholesterol is an essential molecule in all animal life. It has been involved in both normal development and diseases. The Cholesterol/Cholesteryl Ester Quantitation Kit provides a simple method for sensitive quantification of free cholesterol, cholesteryl esters, or both using a colorimetric method. Most of the cholesterol in blood is in the form of cholesteryl ester. These esters can be hydrolyzed to free cholesterol under the appropriate conditions.

Cholesterol/Cholesteryl Ester Kit II:

• Simple procedure with results in ∼1 hour.

The kit is suitable for the quantification of cholesterol/cholesteryl ester in serum, cells and tissue samples.

In the assay, free cholesterol is oxidized by cholesterol dehydrogenase to generate NADH which reacts with a sensitive probe resulting in strong absorbance at A₄₅₀ nm. The assay can detect free or total cholesterol depending upon whether esterase is utilized to hydrolyze cholesterol esters present. Cholesteryl ester can be determined by subtracting the value of free cholesterol from the total cholesterol (cholesterol plus cholesteryl esters). The probe in the kit is more stable, sensitive and specific. The assay can tolerate interferences from various samples significantly.
