Dual-Site cGMP Manufacturing
Gibco® Waymouth's medium 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® Waymouth's product made in our Scotland facility (31220-023). This facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standard. Waymouth's contains no proteins, lipids, or growth factors. Some cell types may required the supplementation with Fetal Bovine Serum (FBS). Waymouth's uses a sodium bicarbonate buffer system (2.24 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.

“This reagent is classified as a medical device in several countries. If it is not regulated as a medical device in specific region, it should be used for laboratory use only.”
For Research Use Only. Not for use in diagnostic procedures.
