Process and medium for mammalian cell culture under low dissolved carbon dioxide concentration

摘要

A cell culture medium which is low in dissolved carbon dioxide is disclosed. The medium contains less than about 1 g/L added sodium bicarbonate and includes an organic buffer and a metal complexing agent. The medium is preferably essentially free of added sodium bicarbonate. Methods of use of the medium in culturing mammalian cells, particularly cells engineered to produce recombinant factor VIII, are also disclosed.
