MEM (Minimum Essential Medium) is one of the most commonly used of all cell culture media. MEM can be used with a variety of suspension and adherent mammalian cells, including HeLa, BHK-21, 293, HEP-2, HT-1080, MCF-7, fibroblasts, and primary rat astrocytes. We offer a variety of MEM modifications for a range of cell culture applications. Find the right formulation using the media selector tool.


This MEM is modified as follows:
WithWithout
• L-glutamine• HEPES
• Phenol Red 


The complete formulation is available.

Using MEM
MEM was developed by Harry Eagle, based on his earlier formulation of Basal Medium Eagle (BME). Many other modifications of MEM followed, including Glasgow’s MEM, MEM α, DMEM, and Temin’s Modification. MEM is available with Earle’s salts for use in a CO2 incubator, or with Hanks' salts for use without CO2. This product is made with Earle’s salts. MEM contains no proteins, lipids, or growth factors. Therefore, MEM requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). MEM 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.

Frequently asked questions (FAQs)

Where can I find the osmolality for MEM Medium?

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

Find additional tips, troubleshooting help, and resources within our Cell Culture Support Center.

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.

I see a decrease in growth of my culture. What should I do?

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.

Abstract
Two adaptor proteins differentially modulate the phosphorylation and biophysics of kv1.3 ion channel by SRC kinase.
Authors: Cook Karen K; Fadool Debra A;
Journal:J Biol Chem
PubMed ID:11812778
'The Shaker family K(+) channel protein, Kv1.3, is tyrosine phosphorylated by v-Src kinase at Tyr(137) and Tyr(449) to modulate current magnitude and kinetic properties. Despite two proline rich sequences and these phosphotyrosines contained in the carboxyl and amino terminals of the channel, v-Src kinase fails to co-immunoprecipitate with Kv1.3 as ... More
Dependence of selective gene activation on the androgen receptor NH2- and COOH-terminal interaction.
Authors: He Bin; Lee Lori W; Minges John T; Wilson Elizabeth M;
Journal:J Biol Chem
PubMed ID:12000757
'The agonist-induced androgen receptor NH(2)- and COOH-terminal (N/C) interaction is mediated by the FXXLF and WXXLF NH(2)-terminal motifs. Here we demonstrate that agonist-dependent transactivation of prostate-specific antigen (PSA) and probasin enhancer/promoter regions requires the N/C interaction, whereas the sex-limited protein gene and mouse mammary tumor virus long terminal repeat do ... More
Acute hippocampal slice preparation and hippocampal slice cultures.
Authors:Lein PJ, Barnhart CD, Pessah IN
Journal:Methods Mol Biol
PubMed ID:21815062
'A major advantage of hippocampal slice preparations is that the cytoarchitecture and synaptic circuits of the hippocampus are largely retained. In neurotoxicology research, organotypic hippocampal slices have mostly been used as acute ex vivo preparations for investigating the effects of neurotoxic chemicals on synaptic function. More recently, hippocampal slice cultures, ... More
The Discodermia calyx toxin calyculin a enhances cyclin D1 phosphorylation and degradation, and arrests cell cycle progression in human breast cancer cells.
Authors:Edelson JR, Brautigan DL
Journal:Toxins (Basel)
PubMed ID:22069692
'Cyclin D1 is a key regulator of the cell cycle that is over expressed in more than half of breast cancer patients. The levels of cyclin D1 are controlled primarily through post-translational mechanisms and phosphorylation of cyclin D1 at T286 induces its proteasomal degradation. To date, no studies have explored ... More
