Dual-Site cGMP Manufacturing:
Gibco Waymouth's Medium 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 Waymouth's Medium product made in our Grand Island facility (11220-035). This facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standards.

Waymouth's Medium contains no proteins, lipids, or growth factors. Some cell types may required the supplementation with Fetal Bovine Serum (FBS). Waymouth's Medium uses a sodium bicarbonate buffer system (2.24 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.
