  • Method for acquiring information of target polypeptide and reagent kit
    Patent number: 11977080
    Abstract: Disclosed is a method for acquiring information of a target polypeptide, comprising: acquiring a diffusion time of a fluorescently labeled target polypeptide and a diffusion time of each of a plurality of fluorescently labeled reference polypeptides by fluorescence correlation spectroscopy or fluorescence cross-correlation spectroscopy, and acquiring information on size of the fluorescently labeled target polypeptide from the diffusion time of the fluorescently labeled target polypeptide with reference to the diffusion times of the plurality of fluorescently labeled reference polypeptides, wherein information on size of each of the plurality of fluorescently labeled reference polypeptides is known, and the sizes of the plurality of reference polypeptides are different from each other.
    Type: Grant
    Filed: April 27, 2021
    Date of Patent: May 7, 2024
    Assignees: NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY, SYSMEX CORPORATION

  • METHOD FOR OBTAINING INFORMATION ON VON WILLEBRAND FACTOR, MEASUREMENT SAMPLE PREPARATION METHOD, AND REAGENT KIT
    Publication number: 20230366819
    Abstract: Disclosed is a method for obtaining information on von Willebrand factor (VWF), comprising the following steps: denaturing, with urea, VWF contained in a biological sample; fluorescently labeling the denatured VWF using a capturing agent that comprises a fluorescent substance and binds to the denatured VWF; and obtaining information on the size of the fluorescently-labeled VWF by fluorescence correlation spectroscopy or fluorescence cross-correlation spectroscopy.
