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.

What is the shelf life of the DMEM, high glucose, pyruvate medium once the bottle is opened and the medium is supplemented?

We do not provide stability data for the product once it is opened as it would depend on the usage and storage conditions.

Is it necessary to store DMEM, high glucose, pyruvate medium in the dark?

Yes, the medium should be stored in the dark because there are some components in the medium such as HEPES, Tryptophan, and Riboflavin, etc. that are sensitive to light.

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.
