Minimum Essential Medium (MEM) α is widely used for mammalian cell culture as well as selection for transfected DHFR negative cells. MEM α can be used with a variety of suspension and adherent mammalian cells, including keratinocytes, primary rat astrocytes, and human melanoma cells. We offer a variety of Gibco™ MEM α modifications for a range of cell culture applications. Find the right formulation using the media selector tool.

Gibco™ MEM α is a modification of Minimum Essential Medium (MEM) that contains non-essential amino acids, sodium pyruvate, lipoic acid, vitamin B12, biotin, and ascorbic acid. MEM α is available without nucleosides for use as a selection medium for DG44 and other DHFR negative cells. Gibco™ MEM α with GlutaMAX™ supplement minimizes toxic ammonia build-up and improves cell viability and growth in an easy-to-use format. This product is made with Earle’s salts.
MEM α contains no proteins, lipids, or growth factors. Therefore, MEM α requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). MEM α uses a sodium bicarbonate buffer system (2.2 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.

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.

Yes. If you suspect that this is the case, remove the medium and add fresh medium. Alternatively, you can supplement medium with growth-promoting components. It is also possible to substitute GlutaMax I or II for glutamine in the medium to prevent glutamine exhaustion.

In all media containing GlutaMAX supplement dipeptides as a substitute for L-glutamine, concentration is equimolar with the L-glutamine in the original formulation.
