Culture your cells with Gibco Minimum Essential Medium
Gibco Minimum Essential Media (MEM), patterned after Eagle’s Media, is one of the most commonly used of all cell culture media and is well suited for the growth of a broad spectrum of mammalian cells. Compared to the earlier Basal Medium Eagle (BME), MEM is formulated with increased concentrations of amino acids. Today there are many other MEM formulations available, including Glasgow’s MEM, MEM α, DMEM, and Temin’s Modification.
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.
MEM composition
Minimum Essential Medium (MEM) contains a higher concentration of amino acids than Basal Medium Eagle (BME). MEM media may be formulated with Earle’s salts for maintenance of pH in a CO2 incubator, or Hanks’ salts for maintenance of pH in atmospheric conditions. Because MEM media lacks proteins, lipids, or growth factors, it commonly requires supplementation with fetal bovine serum (FBS).
Thermo Fisher Scientific offers a variety of MEM modifications for a range of cell culture applications—view an example of a detailed MEM formulation here. Learn about additional MEM formulation options using our Gibco Media selection tool.
Innovative MEM formulations
Take your cell culture to the next level with enhanced MEM formulations. Explore the following formulations that can help improve your cell viability, serum supplementation, transfection experiments, and cold storage constraints.
Advanced MEM
Gibco Advanced MEM is formulated with ingredients that allow for the reduction of serum supplementation by 50–90%, supporting cell growth while lowering your costs and reducing variability caused by lot-to-lot serum changes.
Opti-MEM Reduced Serum Medium
Gibco Opti-MEM Reduced Serum Media, formulated for a reduction in serum supplementation by at least 50%, is ideal for use during cationic lipid transfection—especially with Invitrogen Lipofectamine transfection reagents.
BenchStable MEM
Gibco BenchStable MEM is formulated for storage at room temperature, freeing up valuable cold storage space while supporting cellular proliferation and densities comparable to conventional MEM.
MEM with GlutaMAX supplement
Gibco MEM with GlutaMAX supplement supplies your cells with a stable form of L-glutamine that does not spontaneously degrade in cell culture, improving cell health and viability by reducing the accumulation of toxic ammonia.
