  • Polypeptide and process for measuring living body components using the same
    Patent number: 6828417
    Abstract: A living body component in a sample derived from a living body can be rapidly and accurately measured by reacting the sample with a reagent comprising a combined product of an affinity substance and a polypeptide having at least three acid residues derived from a strong acid, separating the resulting complex by a method applying negative change such as using an anion-exchanger, and determining the amount of the analyte to be measured, on the basis of the amount of the complex or free combined product.
    Type: Grant
    Filed: June 19, 2001
    Date of Patent: December 7, 2004
    Assignee: Wako Pure Chemical Industries, Ltd.
    Inventors: Nobuko Imajo, Yukari Yamagata, Hideo Katoh, Shinji Satomura, Kenji Nakamura
