Abstract
A reagent composition for the quantitative analysis of inorganic phosphorus, composted of xanthosine, purine nucleoside phosphorylase, xanthine oxidase and a color-former. The color-former is a precursor for forming a dye in the presence of hydrogen peroxide and peroxidase. The reagent composition of the invention is improved in storage stability and has a wider determination range. Also provided is a dry analysis element composed of reagent layer containing the inventive reagent composition.
