MODULATION OF CELL GROWTH AND GLYCOSYLATION IN RECOMBINANT GLYCOPROTEIN PRODUCTION

摘要

The present invention relates to methods for selecting between conditions which enhance cell growth or biomass generation and conditions which affect the N-glycosylation maturity of expressed glycoprotein produced by eukaryotic cells under fermentation culture conditions by adjusting the concentrations of iron, copper, zinc and manganses in the medium. Thus, in the methods of the present invention, the glycoprotein producing cells are cultured in a medium which is tailored to a desired end result. The invention also embraces the medium and the use thereof.
