Abstract
The present invention provides a calorimetric method that can perform a simple and reliable analysis in a short time. The method includes transferring an electron from an analyte to a coloring reagent that produces color by reduction via a mediator by using an oxidoreductase; and performing qualitative or quantitative analysis of the analyte by measuring color produced in the coloring reagent. The enzyme reaction of this method is a single stage reaction, and the color production reaction occurs via the mediator. Therefore, the measurement can be performed in a short time. Since this reaction requires neither hydrogen peroxide nor oxygen, the measured values are highly reliable.
