Gibco MEM α is a modification of Minimum Essential Medium (MEM) that contains non-essential amino acids, sodium pyruvate, lipoic acid, vitamin B12, biotin, and ascorbic acid. MEM α is available without nucleosides for use as a selection medium for DG44 and other DHFR negative cells. Gibco MEM α with GlutaMAX supplement minimizes toxic ammonia build-up and improves cell viability and growth in an easy-to-use format. This product is made with Earle’s salts.

Using MEM:
MEM α contains no proteins, lipids, or growth factors. Therefore, MEM α requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). MEM α uses a sodium bicarbonate buffer system (2.2 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.
