Abstract
In accordance with the present invention, CHO cells expressing a recombinant polypeptide of interest are grown in media where the amino acids, vitamins, phosphate, lipids and/or antioxidant optimization is utilized to manipulate and/or control the protein quality attributes of the polypeptides. Polypeptides expressed in accordance with the present invention may be advantageously used in the preparation of pharmaceutical compositions.
