    摘要: An analysis film for assaying transaminase activity comprises a reagent layer containing pyruvic acid oxidase, a combination of a hydrogen donor and a coupler--which is capable of forming a cationic dye--and an anionic polymer. The cationic dye formed by the reaction with a color indicator composition for detecting hydrogen peroxide is fixed with the anionic polymer, thereby mobilization and diffusion of the cationic dye being prevented so that the analysis film achieves high detection sensitivity and high accuracy.

    摘要: 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.
