Classical Media and SaltsDME F12
During the past decade, researchers have reported the culture of a variety of cell lines in serum-free medium that contained, instead of serum, a supplement of nutrients, growth factors and hormones. For example, Mather and Sato reported the successful cultivation of Leydig cells and Sertoli cells in serum-free medium that contained insulin, transferrin,epidermal growth factor, leutinizing hormone or follicle stimulating hormone, somatomedin and growth hormone. Although the hormones and their concentrations are specific for the type of cell under study, the medium found to be most satisfactory for studies of this type was a 1:1 mixture of Dulbecco's Modified Eagle's Medium (DME) and Ham's F-12 Nutrient Mixture. HEPES buffer is included in the formulation at a final concentration of 15 mM to compensate for the loss of buffering capacity incurred by eliminating serum.
Product No. Product Description Application
D6421 Dulbecco's Modified Eagle's Medium/Nutrient F-12 Ham
Liquid

With pyridoxine (substitutes pyridoxine HCl for pyridoxal HCl)
Without L-glutamine, supplement with 0.365 gm/L L-glutamine
Endotoxin tested
Cell culture tested
Sterile-filtered
Liquid form of original 1:1 mixture of DMEM/Ham's F-12, with one important exception. Pyridoxal, which is an aldehyde, has been replaced with pyridoxine. This modification has been shown to improve the stability of the medium.

Suitable for growth of wide range of cell types in low serum conditions.

Cell culture tested
Powder form of original 1:1 mixture of DME/Ham's F-12, supplemented with trace elements.

Trace element supplementation of the original formula (D8900) is required for the compley serum free culture of a wide range of cell types.
D9785 Dulbecco's Modified Eagle's Medium/Nutrient F-12 Ham Base
Powder
With 15 mM HEPES
Without L-glutamine, L-leucine, L-lysine, L-methionine, calcium chloride, magnesium chloride, magnesium sulfate, phenol red and sodium bicarbonate
Supplement with 0.1545 gm/L calcium chloride; 0.365 gm/L L-glutamine; 0.05905 gm/L L-leucine, 0.09125 gm/L L-lysine; 0.0612 gm/L magnesium chloride, 0.04884 gm/L magnesium sulfate, 0.0172 gm/L L-methionine, and 1.2 gm/L sodium bicarbonate

Cell culture tested
The most basic formulation offered. This formulation is used by investigators who want to start with the essential components of (1:1) DME/Ham's F-12, and have the flexibility to optimize the formula for their own application. This base formulation is particularly suitable for studies of cell protein metabolism with label-tagged amino acids.
