cGMP Manufacturing and Quality System
Gibco™ MEM α 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, Life Technologies offers an identical Gibco™ MEM α product made in our Grand Island facility (32561-037). This facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standards.

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.
