Merck, M2279-1L, Minimum Essential Medium Eagle

Minimum Essential Medium Eagle (MEM) is one of the most widely used synthetic cell culture media. It includes higher concentrations of amino acids so the medium more closely approximates the protein composition of cultured mammalian cells. MEM has been used for the cultivation of a wide variety of cells grown in monolayers and attached cell lines, such as fibroblasts, in the presence of fetal bovine serum (FBS), calf, or horse sera.
