DMEM (Dulbecco's Modified Eagle Medium) is a widely used basal medium for supporting the growth of many different mammalian cells. Cells successfully cultured in DMEM include primary fibroblasts, neurons, glial cells, HUVECs, and smooth muscle cells, as well as cell lines such as HeLa, 293, Cos-7, and PC-12. We offer a variety of DMEM modifications for a range of cell culture applications. Find the right formulation using the media selector tool.

Using DMEM
DMEM is unique from other media as it contains 4 times the concentration of amino acids and vitamins than the original Eagle's Minimal Essential Medium. DMEM was originally formulated with low glucose (1 g/L) and sodium pyruvate, but is often used with higher glucose levels, with or without sodium pyruvate. DMEM contains no proteins, lipids, or growth factors. Therefore, DMEM requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). DMEM uses a sodium bicarbonate buffer system (3.7 g/L), and therefore requires a 5–10% CO2 environment to maintain physiological pH.
Manganese is not present in the formulation of our catalog DMEM media products.

Generally speaking, media can be used for up to three weeks after supplementation with serum. There are no formal studies to support this, but it is the rule of thumb used by our scientists.

We routinely ship media that require long-term storage in the refrigerator at room temperature. We have done studies on representative media formulations to show that media can be at room temperature for up to a week without a problem.

Very often mycoplasma contamination cannot be removed from the culture so it should be discarded. You may have a unique culture that you prefer not to discard and would like to try to clean it. Ciprofloxacin and Plasmocin have reportedly been used for this application. If interested in a protocol or directions for use, check with the antibiotic supplier or published literature. Note that mycoplasma are very difficult to remove from culture and spread easily so the treated cultures should be quarantined until clear of mycoplasma, and your laboratory should be thoroughly cleaned.

Try changing the medium or serum. Compare media formulations for differences in glucose, amino acids, and other components. Compare an old lot of serum with a new lot. Increase initial cell inoculums. Lastly, adapt cells sequentially to new medium.
