  • Modification of Minimum Essential Medium (MEM) that contains non-essential amino acids, sodium pyruvate, lipoic acid, vitamin B12, biotin, and ascorbic acid
  • Available without nucleosides for use as selection medium for DG44 and other DHFR-negative cells
  • Made with Earle's salts
  • Contains no proteins, lipids, or growth factors
  • Requires supplementation, commonly with 10% Fetal Bovine Serum (FBS)
  • Uses sodium bicarbonate buffer system (2.2g/L), and therefore requires 5-10% CO2 environment to maintain physiological pH
  • Sustainable packaging
