E199 or Medium 199 with Earle’s Salt is one of the best known media in the history of cell culture. Morgan, Morton and Parker’s Medium 199 was the first really successful attempt to develop a totally defined medium. Medium 199 was originally developed for nutritional studies of chick embryo fibroblasts.
Applications: E199 has broad species applicability, particularly for cultivation of non-transformed cells. 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.
