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.

Modulating lactogenic activity in mammalian cells

The invention concerns methods for preventing the reduction of disulfide bonds during the recombinant production of disulfide-containing polypeptides. In particular, the invention concerns the prevention of disulfide bond reduction during harvesting of disulfide-containing polypeptides, including antibodies, from recombinant host cell cultures.

Prevention of disulfide bond reduction during recombinant production of polypeptides

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 interest, where the cells (e.g., Chinese Hamster Ovary (CHO) cells) have reduced or eliminated activity, e.g., expression, of certain host cell proteins, e.g., enzymes including, but not limited to, certain lipases, esterases, and/or hydrolases.

Modified mammalian cells

The invention concerns methods and means for preventing the reduction of disulfide bonds during the recombinant production of disulfide-containing polypeptides. In particular, the invention concerns the prevention of disulfide bond reduction during harvesting of disulfide-containing polypeptides, including antibodies, from recombinant host cell cultures.

The present invention relates to methods and compositions for preventing incorporation of norleucine into proteins during recombinant protein production in bacteria. The present invention also provides microorganism host cells and nucleic acid molecules for use with the methods and compositions provided herein.

Microorganisms comprising a mutant metA allele for reducing norleucine misincorporation into proteins

Provided herein are methods for preventing the reduction of disulfide bonds during the recombinant production of disulfide-containing polypeptides. In particular, the invention concerns the prevention of disulfide bond reduction during harvesting of disulfide-containing polypeptides, including antibodies, from recombinant host cell cultures.
