    • A method for measuring a glycated protein, a glycated peptide, or a glycated amino acid is provided. In this method, proteolytic activity of the protease is controlled to thereby realize high accuracy of the measurement. Also provided is a reagent used in such a measurement. More specifically, this invention provides a method of measuring a glycated protein, a glycated peptide, or a glycated amino acid comprising the steps of treating a sample containing the glycated protein with a protease for releasing a glycated peptide or a glycated amino acid; reacting the released glycated peptide or glycated amino acid with corresponding oxidase for generation of hydrogen peroxide; and measuring the resulting hydrogen peroxide with peroxidase and an oxidizable color developing reagent; wherein reaction solution before the reaction with the oxidase is adjusted to a pH of 1 to 5; and a reagent used in such measurement.
    • 提供了测定糖化蛋白质,糖化肽或糖化氨基酸的方法。 在该方法中,控制蛋白酶的蛋白水解活性,从而实现高精度的测定。 还提供了用于这种测量中的试剂。 更具体地,本发明提供了测定糖化蛋白质,糖化肽或糖化氨基酸的方法,其包括用用于释放糖化肽或糖化氨基酸的蛋白酶处理含有糖基化蛋白质的样品的步骤; 使释放的糖化肽或糖化氨基酸与相应的氧化酶反应产生过氧化氢; 并用过氧化物酶和可氧化显色试剂测量所得的过氧化氢; 其中将与氧化酶反应之前的反应溶液调节至1至5的pH; 和用于这种测量的试剂。
