This MEM is modified as follows:
|• NEAA||• L-glutamine|
|• Phenol Red||• HEPES|
The complete formulation is available.
MEM was developed by Harry Eagle, and 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 Hank’s 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.
