MEM Alpha with Nucleosides in Earle’s Buffer (MEM-α-N-EBSS)

Background

MEM Alpha with Nucleosides in Earle’s Buffer (MEM-α-N-EBSS) is a suitable nutrient for mammalian cell culture as well as selection for transfected DHFR-negative cells. This media contains nucleoside, and the formulation is available below. depending on cell types, laboratories use MEM-α-N for growing mammalian cell for a variety of suspension as well as adherent cells. Eliminating calcium in this media facilitates the growth of cells in suspension cultures.

Ingredients

MEM Alpha Modification with Nucleosides in Earle’s Buffer (MEM-α-N-EBSS) is a modification of MEM.

Moreover, MEM-α-N-EBSS contains:

  • Non-essential amino acids.
  • Sodium pyruvate.
  • Lipoic acid.
  • Vitamin B12.
  • Biotin and,
  • Ascorbic acid.

Because PurMa™ MEM-α-N-EBSS includes Earles’ Buffer,  it contains:

  1. Calcium chloride
  2. Magnesium sulfate
  3. Potassium chloride
  4. Sodium bicarbonate
  5. Sodium chloride
  6. Sodium Phosphate, monobasic

PurMa™ MEM -α-N-EBSS media also contains:

  • Low level of glucose (1.00 g/ liter)
  • Sodium bicarbonate (2.2 g/L) (if higher than 5% CO2 is used, a higher % of sodium bicarbonate is needed.
  • 2 mM L-glutamine (292 mg/L)’
  • PurMa Biologics manufactures 121 types of MEM -α-N-E

The nucleoside modifies this media  from MEM-α

it contains:

  • Ribonucleosides
  • Deoxyribonucleosides

 

Application

Moreover, this media can also be used for keratinocytes, primary rat astrocytes, as well as human melanoma cells. MEM-α-N-EBSS has also been used for the isolation of mesenchymal stem cells, adipose-derived stem cells, and osteoblasts. Additionally, PurMa™ MEM -α-N-EBSS facilitates the growth and maintenance of primary osteoblast cultures. furthermore, this media performs well for the isolation of polymorphonuclear leukocytes (PMN) from umbilical cord blood.
