cGMP Manufacturing and Quality System:

Gibco™ Medium 199 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. For supply chain continuity, we offer an identical Gibco™ Medium 199 product made in our Scotland facility (22340-020). This facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standard.

Medium 199 contains no proteins, lipids, or growth factors. Medium 199 uses a sodium bicarbonate buffer system (2.2 g/L) and therefore requires a 5–10% CO2 environment to maintain physiological pH.
