Based on a principle that is different to that of a conventional enzymatic method, the present invention provides a novel method for assaying a glycated protein by a simple procedure, within a short period of time, and with high accuracy, and a reagent kit for assaying used in the method. The method for assaying a glycated protein in a sample is realized by treating a glycated protein-containing sample with protease to liberate a glycated peptide, preferably an &#x3b1;-glycated peptide, particularly preferably an &#x3b1;-glycated dipeptide, from a glycated protein, allowing an oxidase to react with the liberated glycated peptide, and determining the produced hydrogen peroxide.

The present invention relates to luminescent playthings such as candles, table lights, pen lights, illumination, illuminating playthings for camp, illuminating playthings for night fishing, fish-gathering lamps, safety candles, neon lights, luminescent inks, luminescent pens, luminescent coatings or luminescent writing implements, in which a soft light of an indescribable tone of color not obtainable from flames of conventional candles is emitted via seawater, lake and marsh water, river water, ground water, tap water or mineral drinking water by utilizing 3 components of luciferin, luciferase and ATP or 4 components of these components plus a metal salt, out of components necessary for bioluminescence in fireflies.
