  • Publication number: 20190376961
    Abstract: A method for measuring fibroblast growth factor-23 (FGF-23) in a sample, which comprise the following steps: (1) reacting, in an aqueous medium, FGF-23 in a sample with magnetic particles, a first antibody or a fragment thereof which binds to FGF-23, and a second antibody or a fragment thereof which binds to FGF-23, to form on the magnetic particles an immunocomplex comprising the first antibody or a fragment thereof which binds to FGF-23. FGF-23, and the second antibody or a fragment thereof which binds to FGF-23; (2) collecting the magnetic particles in the reaction mixture after step (1) by magnetic force, and separating the magnetic particles collected by magnetic force from the other components: and (3) measuring the immunocomplex on the magnetic particles separated in step (2). The present invention provides a method for measuring FGF-23 in a sample, which have a high sensitivity and have a wide measurement range.
