cGMP Manufacturing and Quality System
Gibco® Opti-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 and ISO 9001 standards. For supply chain continuity, Life Technologies offers an identical Gibco® Opti-MEM® product made in our Scotland facility (51985-026). This facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standard.

Gibco® Opti-MEM® uses a sodium bicarbonate buffer system (2.4 g / L) and therefore requires a 5-10% CO₂ environment to maintain physiological pH.
