Medium 199 was originally developed for nutritional studies of chick embryo fibroblasts. It has broad species applicability, particularly for cultivation of non-transformed cells. 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 Medium 199 modifications for a range of cell culture applications. Find the right formulation using the media selector tool.

Using Medium 199
Compared to other basal media, Medium 199 contains unique components, including adenine, adenosine, hypoxanthine, thymine, and additional vitamins. Medium 199 is available with Earle's salts for use in a CO2 incubator, or with Hanks' salts for use without CO2. This product contains Earle's salts. 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.
