Description

The advantages of MEM-α-Advance in HBBS over MEM-α 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.
• Improves the culture of primary cells.

Mechanism

Although L-glutamine is a vital amino acid, it degrades, generating 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 GMP Bioscience  GluaSup  is a combination of L-alanyl-L-glutamine that prevents the degradation of L-glutamine.

MEM Alpha-Modification Advance (MEM-α-Advance) in Hanks’ Buffer contains:

• 5 mM sodium pyruvate
• High glucose (4.5g/L)
• Non-Essential Amino Acids
• 3.7 g/L Sodium Bicarbonate; GMP Bioscience Manufactures several types of MEM-α-Advance based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
• Phenol Red

MEM-α-Advance in HBBS contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).
