  • Method of recovering peptide and method of detecting peptide
    Patent number: 9840535
    Abstract: Disclosed is a method of recovering a peptide, including: mixing a liquid sample containing a complex of peptide and protein in blood with a reagent containing a neutral amino acid, an acidic amino acid or both the neutral and acidic amino acids to liberate the peptide from the protein in blood; and recovering the liberated peptide.
    Type: Grant
    Filed: January 14, 2015
    Date of Patent: December 12, 2017
    Assignee: SYSMEX CORPORATION
    Inventor: Kana Kawasaki
  • Method of recovering peptide and method of detecting peptide
    Patent number: 9624263
    Abstract: Disclosed is a method of recovering a peptide including: mixing a liquid sample containing a complex of peptide and protein in blood with a reagent containing at least one selected from the group consisting of Zn2+, Ca2+, Li+, Ba2+, Mg2+, Mn2+, and a metal compound that forms any of these metal ions to liberate the peptide from the protein in blood; and recovering the liberated peptide.
    Type: Grant

  • Method of liberating and recovering peptide
    Patent number: 8716440
    Abstract: A novel method capable of liberating a peptide from a complex of peptide and albumin and the associated method of recovering the peptide are provided. When a liquid sample containing a complex of peptide and albumin undergoes heat treatment, a self-aggregate of albumin formed in the liquid sample. The peptide is simultaneously liberated from the complex and recovered by removing the self-aggregate from the liquid sample.
