MÉTHODE DE MESURE DU CHOLESTÉROL DANS UNE LIPOPROTÉINE DE FAIBLE DENSITÉ, RÉACTIF DE MESURE ET KIT DE MESURE

摘要

To provide a method for simply and precisely measuring cholesterol (LDL-C) in low-density lipoprotein in a sample without use of any surfactant having an alkylphenol structure, in terms of environmental friendliness. A method for measuring LDL-C in a sample, the method comprising: reacting the sample with (i) a combination of cholesterol ester hydrolase and cholesterol oxidase or (ii) a combination of cholesterol ester hydrolase, an oxidized coenzyme and cholesterol dehydrogenase, in an aqueous solvent which comprises: [a] one or more surfactants selected from the group consisting of a polyoxyethylene alkyl ether and a polyoxyethylene polyoxypropylene alkyl ether; and [b] a polyoxyethylene polyoxypropylene copolymer; and which does not comprise any surfactant having an alkylphenol structure; and measuring a substance formed or consumed in the reaction.
