  • High-cell density fed-batch fermentation process for producing recombinant protein
    Patent number: 10301663
    Abstract: Methods for producing proteins, for example, recombinant meningococcal 2086 proteins, using fed-batch fermentation with continuous input of an inducer after achieving a threshold parameter, and continuous input of a carbon source, for example, a constant rate input, to improve protein yields, as well as high density protein compositions for use in the methods of the present invention, are provided.
    Type: Grant
    Filed: February 1, 2016
    Date of Patent: May 28, 2019
    Assignee: Wyeth, LLC
    Inventors: Wei-Qiang Willie Sun, Earl Joseph Pursell
