  • Chromatographic method for collecting blood coagulation factor VII with high yield
    Patent number: 11952398
    Abstract: A chromatographic method for collecting blood coagulation factor VII (Factor VII) and/or activated blood coagulation factor VII (activated Factor VII) from plasma-derived fractions with high yield is provided. In accordance with the method of the present invention, Factor VII and/or activated Factor VII of interest can be collected with a recovery rate of as high as 90% or more by letting Factor VII and/or activated Factor VII which fails to be adsorbed to a first anion exchange resin and remains in a non-adsorption fraction be adsorbed in a second anion exchange resin.
    Type: Grant
    Filed: June 9, 2021
    Date of Patent: April 9, 2024
    Assignee: KM Biologics Co., Ltd.
    Inventors: Kentaro Ebisu, Takashi Kai, Nozomi Matsuo
