Minimum Essential Medium (MEM) 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 Gibco® MEM modifications for a range of cell culture applications. Find the right formulation using our media selector tool.
This MEM is modified as follows:
With
Without
• Phenol red
• L-glutamine
• 6 g/L D-glucose
• HEPES
• 3.7 g/L sodium bicarbonate
Gibco® 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. MEM is available with Earle's salts for use in a CO2 incubator, or with Hanks' salts for use without CO2.

cGMP Manufacturing and Quality System Gibco® MEM is manufactured at a cGMP compliant facility, located in Grand Island, New York. The facility is registered with the FDA as a medical device manufacturer and is certified to ISO 13485 standards.
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.
