DMEM is unique from other media as it contains 4 times the concentration of amino acids and vitamins than the original Eagle's Minimal Essential Medium. DMEM was originally formulated with low glucose (1 g/L) and sodium pyruvate, but is often used with higher glucose levels, with or without sodium pyruvate.

cGMP Manufacturing and Quality System：
Gibco DMEM is manufactured at a cGMP compliant facility, located in Paisley, Scotland, UK. The facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standard. For supply chain continuity, we offer a comparable Gibco DMEM product made in our Grand Island facility (12100-061). This facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standards.

DMEM contains no proteins, lipids, or growth factors. Therefore, DMEM requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). DMEM uses a sodium bicarbonate buffer system (3.7 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.

Powder forms of Gibco cell culture medium require sodium bicarbonate supplementation, pH adjustment, and filtration at the time of preparation.
