MEM - Minimum Essential Media
Minimum Essential Medium (MEM) was developed by Harry Eagle and is one of the most widely used medias of all synthetic cell culture media. MEM is simply a modified Basal Medium Eagle media containing higher concentrations of essential nutrients. MEM has been utilized for the cultivation of a variety of cells grown in monolayers. The optional supplementation of non-essential amino acids (NEAA) to the formulations that incorporate either Hanks’ or Earle's salts has broadened the usefulness of this medium.
