ABSTRACT:
A dry-type multilayer analytical element containing a color reagent composition comprising an oxidase specifically reaction with an analyte or derived therefrom to produce hydrogen peroxide, hydrogen peroxide-decomposing enzyme, an alkali metal salt of ferrocyanide and a chromogen which is separated from the hydrogen peroxide-decomposing enzyme, the chromogen being incorporated in a layer nearer to the transparent support of the analytical element than the layer containing the hydrogen peroxide-decomposing enzyme. The analytical element exhibits excellent coloration, color stability, and accuracy and the results are minimally influenced by the presence of hemoglobin in the sample.
