Advantages
MEM-α performs better than MEM for a number of cell lines, please see the description of regular MEM-α: MEM-a in Earle’s Buffer
The advantages of MEM-α-Advance in EBBS 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.
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 Advance 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 Earle’s 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 EBBS contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).
