  • Production of galactosylated glycoproteins in lower eukaryotes
    Patent number: 8815544
    Abstract: The present invention provides a novel lower eukaryotic host cell producing human-like glycoproteins characterized as having a terminal ?-galactose residue and essentially lacking fucose and sialic acid residues. The present invention also provides a method for catalyzing the transfer of a galactose residue from UDP-galactose onto an acceptor substrate in a recombinant lower eukaryotic host cell, which can be used as a therapeutic glycoprotein.
    Type: Grant
    Filed: July 21, 2010
    Date of Patent: August 26, 2014
    Assignee: Glycofi, Inc.
    Inventors: Robert Davidson, Tillman Gerngross, Stefan Wildt, Byung-Kwon Choi, Juergen Hermann Nett, Piotr Bobrowicz, Stephen Robin Hamilton
