Medium 199 is widely used in virology, vaccine production, and in vitro cultivation of primary explants of mouse pancreatic epithelium, and rat lens tissues. We offer a variety of Gibco™ Medium 199 modifications for a range of cell culture applications. Find the right formulation using the media selector tool.

cGMP Manufacturing and Quality System
Gibco™ Medium 199 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.

Medium 199 contains no proteins, lipids, or growth factors. This Medium 199 uses a sodium bicarbonate buffer system (1.25 g/L) and therefore requires a 3-5% CO₂ environment to maintain physiological pH.
