One of the most widely used of all synthetic culture media is Minimum Essential Medium Eagle (MEM). MEM provides basic nutrients for the cultivation of many cells grown in monolayers. Due to high concentrations of amino acids MEM closely approximates the composition of proteins of mammalian cells. Tico Europe offers MEM with either Earle’s or Hanks’ salts which optimizes the usefulness of this medium. The best formulation of MEM for your cells depends on the type of cell to be grown and the used culture system.
