Description

Background

MEM Alpha Modification in Earle’s Buffer (MEM-α) is certainly a suitable nutrient for mammalian cell culture as well as selection for transfected DHFR-negative cells. MEM -α Modification is widely used for primary osteoblast cultures as well as isolation of polymorphonuclear leukocytes (PMN) from umbilical cord blood. Eliminating calcium in this media facilitates the growth of cells in suspension cultures.

MEM Alpha Modification in Earle’s Buffer (MEM-α)  contains

  • Non-essential amino acids.
  • Sodium pyruvate.
  • Lipoic acid.
  • Vitamin B12.
  • Biotin and,
  • Ascorbic acid.
  • Also, MEM Alpha Modification in Earle’s Buffer (MEM-α) does not contain deoxyribonucleosides and ribonucleosides.
  • Moreover, PurMaTM MEM-α media in Earle’s buffer includes Earles’ buffer

The composition of Earle’s buffer, it contains:

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

Additionally, MEM Alpha Modification in Earle’s Buffer (MEM-α)

it contains:

  • Low level of glucose (1.00 g/ liter)
  • More importantly, 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)
  • Also, PurMa Biologics manufactures 118 types of MEM-α

Application

This media can also be used with a variety of suspension and adherent cells including keratinocytes, primary rat astrocytes as well as human melanoma cells. Furthermore, MEM Alpha Modification in Earle’s Buffer (MEM-α) has also been used for the isolation of mesenchymal stem cells, adipose-derived stem cells, and osteoblast.

Frequently asked questions

How should I store MEM Alpha Modification in Earle’s Buffer (MEM-α)?

Store at 2 to 8 degrees C, protected from light, and do not freeze unless the label states otherwise. Freezing can precipitate salts and degrade light sensitive components such as riboflavin and folic acid. Always follow the storage line on the Certificate of Analysis for the specific lot.

What is the shelf life once opened?

Unopened and correctly stored, the typical shelf life is 12 months from manufacture. Once opened, use within about four weeks and always handle in a laminar flow hood, since the practical limit after opening is contamination risk rather than chemical stability.

Is it sterility and endotoxin tested?

Yes. Every lot is sterile filtered and tested for sterility and endotoxin, and a Certificate of Analysis is issued for each lot. The COA is available on request for any catalogue number.

Do I need to add L-glutamine?

It depends on the formulation you order. Standard formulations may contain free L-glutamine, which degrades in solution over time, while MAX formulations use a stable L-alanyl-L-glutamine dipeptide that does not require fresh supplementation. Check the option you have selected before adding more.

Can I order this in bulk or as a custom formulation?

Yes. Bulk volumes and custom formulations are made to order, including adjusted glucose, bicarbonate, buffering and cation content. Use the request bulk pricing button on this page and include the specification you need.
