  • Cell culture medium
    Patent number: 9243224
    Abstract: A cell culture medium with high content of choline chloride is provided. The cell culture media further comprise only moderate amounts of amino acids, in particular the amount of glutamine in the cell culture media is limited. The cell culture media can be used for large scale production of polypeptides using cell cultures. The cell culture media with high content of choline chloride are particularly suitable for fed-batch cell culture whereby cell viabilities stay at a higher level for a longer time and high polypeptide titers although limited amounts of amino acids are used.
    Type: Grant
    Filed: February 12, 2015
    Date of Patent: January 26, 2016
    Assignee: Novartis AG
    Inventors: Wolfgang Ernst Gustav Budach, Helene C. Chassin, Kerstin Dorsch
