MEM Alpha Modification (MEM-α) in Hanks’ Buffer

Background

MEM Alpha Modification (MEM-α) in Hanks’ Buffer is certainly a suitable choice for mammalian cell culture as well as selection for transfected DHFR-negative cells. Besides, this media can also be used with a variety of suspension and adherent cells including keratinocytes, primary rat astrocytes, and human melanoma cells.  Furthermore, it is important that eliminating calcium in this media facilitates the growth of cells in suspension cultures.

Ingredients

MEM -α has improved regular MEM as it contains:

  • Non-essential amino acids.
  • Sodium pyruvate.
  • Lipoic acid.
  • Vitamin B12.
  • Biotin and,
  • Ascorbic acid.
  • Also, MEM-α does not contain deoxyribonucleosides and ribonucleosides.

Moreover, PurMa™ MEM -α media in Hank’s buffer includes HBSS

Composition of HBSS buffer contains:

  • Potassium Chloride
  • Potassium Phosphate, monobasic
  • Sodium Bicarbonate
  • Sodium Chloride
  • Sodium Phosphate, dibasic
  • Low level of glucose (1.00 g/ liter)
  • Sodium bicarbonate (0.35 g/L)
  • 2 mM L-glutamine (292 mg/L)
  • Low level of glucose (1.00 g/ liter)

Furthermore, PurMa Biologics manufactures 123 types of MEM with HBSS buffer

Application

Alpha modification of Minimum Essential Medium Eagle certainly makes an excellent for the isolation of mesenchymal stem cells, adipose-derived stem cells as well as osteoblast. MEM -α Modification is widely used for primary osteoblast cultures as well as isolation of polymorphonuclear leukocytes (PMN) from umbilical cord blood.
