Minimum Essential Medium (MEM) is a modification of Basal Medium Eagle (BME). Developed by Harry Eagle, it was designed to meet the specific nutritional requirements of certain subtypes of Hela cells and normal mammalian fibroblasts. MEM includes higher concentration of amino acids so as to closely approximate the protein composition of cultured mammalian cells. MEM can be used either with Earle's salts or Hank's salts and can also be additionally supplemented with non-essential amino acids (NEAA). This medium can be further modified by eliminating calcium to facilitate growth of cells in suspension cultures. HEPES is a zwitterionic buffer having a pKa of 7.3 at 37ºC, which prevents the initial rise in pH that tends to occur at the initiation of a culture and increases the buffering capacity of the medium.
