Abstract

See full text

Provided is a method for separately or simultaneously quantifying whole HDL-C and cholesterol in HDL subfractions: ApoE-Containing HDL-C and ApoE-deficient HDL-C. A method for enzymatically and separately quantifying cholesterol in the ApoE-deficient HDL comprising: adding a surfactant composed of a polyoxyethylene benzyl phenyl ether derivative to a test sample in a final concentration of 0.05 to 0.10%, reacting the test sample with cholesterol esterase and cholesterol oxidase, and quantifying hydrogen peroxide generated. A method for enzymatically and separately quantifying cholesterol in ApoE-Containing HDL comprising: adding a surfactant composed of a polyoxyethylene benzyl phenyl ether derivative so as to obtain a final concentration of 0.15 to 0.75%, reacting the test sample with cholesterol esterase and cholesterol oxidase, and quantifying hydrogen peroxide generated.
