  • COMPOSITION FOR ASSAYING GLYCATED PROTEINS
    Publication number: 20120129202
    Abstract: Compositions for accurately assaying a glycated protein by: 1) avoiding effects of globulin and ascorbic acid components, 2) stabilizing proteases and at least enzymes acting on glycated amino acids; 3) accurately assaying albumin; and 4) assaying glycated albumin while avoiding the effects of glycated hemoglobin, and an assay method are provided. Thus, the contents of a glycated protein and glycated albumin can be more accurately determined.
    Type: Application
    Filed: December 9, 2011
    Publication date: May 24, 2012
    Inventors: Takuji Kouzuma, Issei Yoshioka, Motoo Arai, Junichi Sumitani, Shigeyuki Imamura
  • Composition for assaying glycated proteins
    Patent number: 8105800
    Abstract: Composition for accurately assaying a glycated protein by: 1) avoiding effects of globulin and ascorbic acid components, 2) siabilizing proteases and at least enzymes acting on glycated amino acids; 3) accurately assaying albumin; and 4) assaying glycated albumin while avoiding the effects of glycated hemoglobin, and an assay method are provided. Thus, the contents of a glycated protein and glycated albumin can be more accurately determined.
