Gibco DMEM / F-12 is a 1:1 mixture of DMEM and Ham's F-12. This formulation combines DMEM's high concentrations of glucose, amino acids and vitamins with F-12's wide variety of components.

Using DMEM/F-12：
DMEM / F-12 contains no proteins, lipids, or growth factors. Therefore, DMEM / F-12 may require supplementation, commonly with 10% Fetal Bovine Serum (FBS). DMEM / F-12 uses a sodium bicarbonate buffer system and therefore requires a 5-10% CO2 environment to maintain physiological pH.

Powder forms of Gibco cell culture medium require sodium bicarbonate supplementation, pH adjustment, and filtration at the time of preparation (see protocol for details).
