Cholesterol/ Cholesteryl Ester Assay Kit ab65359 provides a
simple method for sensitive quantification of total cholesterol, free
cholesterol, and cholesteryl esters, by colorimetric or fluorometric methods.
How the assay works
The majority of cholesterol in blood is in the form of cholesteryl esters. In
the cholesterol assay protocol, these are hydrolyzed to cholesterol by
cholesterol esterase. Cholesterol is then oxidized by cholesterol oxidase to
yield hydrogen peroxide. Hydrogen peroxide is then processed by an enzyme
causing a reaction with a probe to generate red color (λmax = 570 nm) and
fluorescence (Ex/Em = 535/587 nm).
The assay detects total cholesterol (cholesterol and
cholesteryl esters) when cholesterol esterase is included in the reaction, or
free cholesterol when it is not included. The amount of cholesteryl ester can
be determined by subtracting the value of free cholesterol from the total
(cholesterol plus cholesteryl esters).
Cholesterol assay protocol summary
- -
Add samples and standards to wells.
- -
Add total cholesterol reaction mix (with esterase) or free cholesterol
reaction mix (without esterase) and incubate for 60 min at 37°C.
- -
Analyze with microplate reader.
