Dry-type multilayer analytical element.

摘要

In a dry-type multilayer analytical element containing a color reagent composition comprising an oxidase specifically reacting with an analyte or derived therefrom to produce hydrogen peroxide, hydrogen peroxide-decomposing enzyme, an alkali metal salt of ferrocyanide and a chromogen, this chromogen is separated from the hydrogen peroxide-decomposing enzyme, and the chromogen is incorporated in a layer nearer than the layer containing the hydrogen peroxide-decomposing enzyme to the transparent support of the analytical element. This analytical element is excellent in coloration, particularly stability of the color formed, and its result is accurate. Moreover, the results is hardly influenced by the presence of hemoglobin in a sample.
