MEM Eagle (also called EMEM) was developed in 1959 for cultivation of HeLa and L cells. Amino acid concentrations conform closely to the protein composition of human cells. Higher concentrations of nutrients permit longer periods between feedings. EMEM has vitamin concentrations 2-5X greater than BME and higher amino acid concentrations than BME. EMEM is suitable for culturing a broad spectrum of mammalian cells.

MEM Eagle is available with Hanks' or Earle's salts.
MEM-Hanks (12-127F or 12-137F) does not a require CO2 enriched atmosphere. 
Joklik's modification is intended for suspension culture.

Storage = 2ºC to 8ºC
                (or 15-30ºC for products 12-125, 12-136, 12-684, 12-668, 12-127 and 12-137)
