  • Publication number: 20210371809
    Abstract: Provided herein is are methods of preventing loss of copper in a solution. The solution is a cell culture medium, cell culture feed or cell culture additive comprising copper (II) and cysteine. The method comprises having substantially the same amount of soluble copper before and after filtering the solution. Also provided are methods of preparing a cell culture medium, cell culture feed or cell culture additive comprising copper (II), cysteine, and other components, without loss of soluble copper. Also provided are methods of culturing a cell or making a biological product comprising use of media prepared according to said methods of preventing loss of copper or preparing said media. Further provided is media prepared according to said methods and use of such media.

  • Publication number: 20210009988
    Abstract: The present disclosure relates to methods, cells and compositions for producing a product of interest, e.g., a recombinant protein. In particular, the present disclosure provides improved mammalian cells expressing the product of interests, where the cells (e.g., Chinese Hamster Ovary (CHO) cells) have modulated lactogenic activity. The present disclosure also relates to methods and compositions for modulating pyruvate kinase muscle (PKM) expression (e.g., PKM-1 expression) in a mammalian cell to thereby reduce or eliminate the lactogenic activity of the cell, as well compositions comprising a cell having reduced or eliminated lactogenic activity and methods of using the same.
