MEM α (Minimum Essential Medium 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 MEM α modifications for a range of cell culture applications. Find the right formulation using the media selector tool.

This MEM α is modified as follows:

With: Phenol Red, L-glutamine

Without: Ribonucleosides, Deoxyribonucleosides

The complete formulation is available.

Using DMEM α

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. 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.

For Research Use or Further Manufacturing. Not for diagnostic use or direct administration into humans or animals.

よくあるご質問（FAQ）

What is the difference between MEM α, nucleosides and MEM α, no nucleosides?

Our MEM α, nucleosides is widely used for mammalian cell culture as well as selection for transfected DHFR-negative cells.
Our MEM α without nucleosides can be used a selection medium for DG44 and other DHFR-negative cells (DHFR = dihydrofolate reductase).
DHFR-negative cells are unable to grow unless the culture medium is supplemented with essential metabolites, including hypoxanthine and thymidine.

Where can I find the osmolality for MEM Medium?

The osmolality is listed in the COA for the particular lot number of the medium.

How long can I keep my media after supplementing with serum?

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.

My medium was shipped at room temperature but it is supposed to be stored refrigerated. Is it okay?

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.

How can I remove mycoplasma contamination from my cell culture medium?

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.

Abstract
Gene expression analysis of the pleiotropic effects of TGF-ß1 in an in vitro model of flexor tendon healing.

'Flexor tendon injuries are among the most challenging problems for hand surgeons and tissue engineers alike. Not only do flexor tendon injuries heal with poor mechanical strength, they can also form debilitating adhesions that may permanently impair hand function. While TGF-ß1 is a necessary factor for regaining tendon strength, it ... More
