  • Recombinant factor X with no glycosylation and method for preparing the same
    Patent number: 8679783
    Abstract: A Factor X (hereinafter referred to as “FX”) with a high activity is provided. The present invention relates to a method for efficiently preparing a recombinant, two-chain FX which comprises intervening glycosylation at such an amino acid sequence that is essential for glycosylation in FX to thereby allow for expression of a recombinant FX with no glycosylation, and the recombinant FX with no glycosylation obtained by said method.
    Type: Grant
    Filed: February 24, 2012
    Date of Patent: March 25, 2014
    Assignee: The Chemo-Sero-Therapeutic Research Institute
    Inventors: Kenji Soejima, Takayuki Imamura, Ryoichi Kawamura, Hiroshi Nakatake, Arisa Maeyashiki, Hitomi Togo
