Overview

Introduction
Cholesterol concentration in serum is known to be closely related with production, absorption and dissimilation in liver and intestinal tract, and lipoprotein metabolism in blood.
LabAssay™ Cholesterol is able to measure total cholesterol in mouse serum by an enzyme reaction using N-Ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethoxyaniline sodium salt (DAOS).
Assay principle
Cholesterol esters in the sample are decomposed into free cholesterol and fatty acid by cholesterol esterase, when the sample reacts with chromogen reagent. The cholesterol is oxidized with existing free cholesterol by cholesterol oxidase, and simultaneously hydrogen peroxide is produced. The produced hydrogen peroxide let DAOS and 4-Aminoantipyrin oxidize and condensate quantitatively by peroxidase (HRP), which produces a blue pigment. Quantitation of total cholesterol in the sample can be made by measurement of the absorbance.
