  • Method of liberating peptide and method of recovering peptide
    Patent number: 10053488
    Abstract: Disclosed is a method of liberating a peptide, the method comprising a step of bringing a self-aggregate of albumin containing a peptide incorporated therein into contact with a solution that contains a compound represented by Formula (I) or (II) defined in the specification at a concentration of 80 mM to 1000 mM and allowing the peptide to be liberated from the self-aggregate of albumin into the solution.
    Type: Grant
    Filed: August 24, 2016
    Date of Patent: August 21, 2018
    Assignee: SYSMEX CORPORATION
    Inventors: Rena Tsuruoka, Sanai Tsunokuni, Yukiko Miura, Hiroyuki Kabata
  • 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
