  • Patent number: 7588910
    Abstract: There is provided a method for specifically determining a glycated ?-chain N-terminal of glycated hemoglobin using enzymes without a separation operation, and a determination reagent kit therefor. A protease that cleaves a glycated amino acid and/or a glycated peptide from a glycated ?-chain N-terminal without substantially cleaving a glycated amino acid or a glycated peptide from a glycated ?-chain N-terminal of glycated hemoglobin or a fragment thereof is screened. The method of specifically determining a glycated ?-chain N-terminal of glycated hemoglobin and the determination reagent kit are provided by using the protease obtained by the screening method. According to the present invention, a glycated ?-chain N-terminal of glycated hemoglobin can specifically be determined without a separation operation.

  • Publication number: 20090042279
    Abstract: It is intended to provide a noninvasive method of conveniently detecting mild impaired glucose tolerance and/or insulin hyposecretion at the early stage with the use of an enzyme. Namely, mild impaired glucose tolerance and/or insulin hyposecretion at the early stage are detected by quantifying myoinositol secreted into the urine before loading glucose and after loading glucose for a definite period of time with the use of a reagent and comparing the increase (or the increase ratio) in the myoinositol content thus measured with a characteristic level which has been preliminarily determined in normal subjects.

  • Publication number: 20080295259
    Abstract: Provided are a method of stabilizing a leuco dye storable as a liquid for a long time, a method of reducing nonspecific color development thereof at a time of a color development reaction, and a stable liquid reagent composition using the methods. The inventors of the present invention found that coexistence of the leuco dye with a specific reducing agent resulted in suppression of self color development and its remarkably improved stability in a solution, and that when a color development reaction of the leuco dye with hydrogen peroxide was performed, coexistence of the leuco dye, in a reaction solution, with another dye which had an absorption spectrum not influencing a measurement wavelength of the leuco dye and did not react with hydrogen peroxide suppressed nonspecific color development and lowered a reagent blank value, which was applied to an analytical reagent.
