Description

Dulbecco′s Modified Eagle′s Medium-MAX (DMEM-MAX)

Background:

Dulbecco′s Modified Eagle′s Medium-MAX (DMEM-MAX) is a commonly used media for Mammalian cell culture.

Advantages:

Dulbecco′s Modified Eagle′s Medium-MAX (DMEM-MAX) over DMEM:

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.

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 which prevents degradation of L-glutamine.

Contents:

Dulbecco′s Modified Eagle′s Medium-MAX (DMEM-MAX) 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 DMEM -MAX based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
•     Phenol Red

DMEM-MAX contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).
