The present invention relates to methods of reducing substitution of amino acids during the production of polypeptides of interest in mammalian cells. By varying the concentration of amino acids in the culture medium, heterogeneity of the polypeptide's amino acid sequence is decreased, leading to higher yields of functional protein.
