Patent ID: 8859221

Claim:
A dry analytical element for high density lipoprotein cholesterol (HDL-C) detection which consists of a water-impermeable support, an adhesive layer which is composed of gelatin, and a porous developing layer which is composed of polyester or polysulfone, wherein the porous developing layer comprises cholesterol esterase derived from Schizophyllum commune , cholesterol oxidase derived from Pseudomonas sp., a surfactant that preferentially dissolves high density lipoprotein (HDL), peroxidase and chromogens, wherein the surfactant that preferentially dissolves HDL is polyoxyethylene alkylene phenyl ether or polyoxyethylene alkylene tribenzyl phenyl ether, and wherein the chromogens are 4-aminoantipyrine or a derivative thereof and a Trinder reagent that couples with the 4-aminoantipyrine or the derivative thereof.
