Dulbecco's MEM/Ham's F-12 (1:1 mixture) liquid and powder medium
The (1:1) mixture has improved levels of different nutrients through the contribution of Ham's F-12. It has found utility for the growth of a wide range of mammalian cells when supplemented with growth factors, hormones or serum (e.g to grow human proteins such as erythropoetin).
Different from the original formulation, only 0.05 mg/l riboflavin is used to avoid negative photo oxidative effects.
