MEM Alpha-Modification with Nucleosides MAX in Earle’s Buffer (MEM-Alpha-N-MAX)
$41.61 – $663.94
MEM α-Modification with Nucleosides MAX in Earle’s Buffer (MEM-α-N-MAX-EBBS) contains L-Alanyl-L-Glutamine. Additionally, MEM-α-N-MAX (EBBS) significantly improves cell viability and growth. We manufacture several types of MEM-α-N-MAX based on your requirements.
Description
MEM α-Modification with Nucleosides MAX in Earle’s Buffer (MEM-α-N-MAX-EBBS)
Background
MEM α-Modification with Nucleosides MAX in Earle’s Buffer (MEM-α-N-MAX-EBBS) is a commonly used media for Mammalian cell culture.
Advantages
The advantages of MEM-α-N-MAX over MEM-α-N are:
- Higher PH Capacity
- Moreover, it contains 4 mM L-Alanyl-L-Glutamine (0.869 g/L) instead of L-Glutamine and therefore:
- Possess longer shelf life.
- More importantly, minimizes toxic ammonia build-up.
- Significantly improves cell viability and growth.
- Remains stable across a wide range of temperatures.
- Consequently, it improves the culture of primary cells.
Mechanism
Although L-glutamine is a vital amino acid, it degrades, resulting in the generation of toxic ammonia and pyrrolidine carboxylic acid. One way to minimize L-glutamine degradation in media is to gradually add these amino acids to your cell culture. However, keeping track of time to keep the amount of L-glutamine at the same level is tedious, if not impossible.
Alternatively, L-alanyl-L-glutamine can be used because it is much more stable in aqueous solutions. More importantly, it does not easily degrade and gradually releases aminopeptidases. As a result, L-glutamine and L-alanine are then used by the cells for protein production in the TCA cycle.
In addition to our Max formulation products, we manufacture PurMaTM GluaSup (Cat# P3S210 559) is a combination of L-alanyl-L-glutamine that prevents the degradation of L-glutamine.
Contents
MEM α-Modification with Nucleosides MAX in Earle’s Buffer (MEM-α-N-MAX-EBBS) contains:
- 5 mM sodium pyruvate
- High glucose (4.5g/L)
- Non-Essential Amino Acids
- 3.7 g/L Sodium Bicarbonate; PurMa Biologics Manufactures several types of MEM-α-N-MAX (EBBS) based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
- Phenol Red
PurMa™ MEM-α with nucleosides MAX (MEM-α-N-MAX) is modified from MEM-α-MAX with the following ingredients:
- Ribonucleosides
- Deoxyribonucleosides
MEM-α-N-MAX (EBBS) contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).
