Abstract

PURPOSE:To obtain the subject testing paper capable of rapidly and simply determining cholesterol amount in blood by sight by adding cholesterol oxidase, peroxidase and H2O2 color former to a filter paper. CONSTITUTION:A filter paper for quantitative or qualitative analysis or chromatography is dipped into an aqueous solution of oxygen-color former consisting of 10ml phosphoric aid buffer having pH 6-8, 5-40 unit cholesterol oxidase, 0.1-20 unit peroxidase, 10-200mug H2O2 color former (e.g. 3,3,- diaminobenzidine.-4HCl) and 10ml water and preferably further 1-5% aqueous solution of polyvinyl pyrrolidone (of 10ml as total amount of water and the above-mentioned aqueous solution) for 10-60sec and pulled up and then subjected to freeze drying to provide the testing paper.
