Temin's Modified Eagle Medium (MEM), is a modified form of Minimum Essential Medium, 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 Gibco™ 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
• Earle's salts• Phenol Red
• Sodium Bicarbonate 


The complete formulation is available.

MEM, developed by Harry Eagle, was 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. Temin’s Modification is a 2x MEM with 4x the vitamins and amino acids of the original MEM. This MEM formulation contains Earle’s salts for use in a CO2 incubator. This product is made with Earle’s salts.

Product Intended Use
For in vitro diagnostic use. CAUTION: Not for human or animal therapeutic use. Uses other than the intended use may be a violation of local law.

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 (8.4 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.

For Research Use Only. Not for use in diagnostic procedures. Not for human or animal therapeutic use. Uses other than the intended use may be a violation of local law. For in vitro diagnostic use.

Frequently asked questions (FAQs)

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.

My cells are not adhering to the culture vessel. What should I do?

This can occur if cells are overly trypsinized. Trypsinize for a shorter time or use less trypsin. Mycoplasma contamination could also cause this problem. Segregate your culture and test for mycoplasma infection. Lastly, check for attachment factors in the medium.
