ABSTRACT:
Disclosed is a method of improving protein production in protein-producing cell cultures. The method comprises the steps of culturing protein-producing cells in a medium comprising essential nutrients, vitamins, salts and amino acids, modified by the addition of increased amounts of amino acids so that the osmolarity of the medium is hypertonic, i.e., above about 340 milliosmoles, preferably within the range of 340 to 450 milliosmoles and most preferably 360 milliosmoles. Cells grown in such media produce protein at levels on the order of four times the protein production in normal, isotonic media.
