Gibco® Richter's MEM is a modified formulation of Eagle's MEM that contains iron, zinc, putrescine, fatty acids, and gentamycin. Richter's modification also includes very high concentrations of both choline chloride and i-Inositol. This product was further modified with L-glutamine, without gentamicin sulfate, and without phenol red.

Product Use
For Research Use Only. Not for use in diagnostic procedures.

Dual-Site cGMP Manufacturing
Gibco® Richter's MEM is manufactured at a cGMP compliant facility, located in Grand Island, New York. The facility is registered with the FDA as a medical device manufacturer and is certified to ISO 13485 standards.

Gibco® 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.
