Leibovitz’s L-15 Medium – MAX
Leibovitz’s L-15 Medium – MAX significantly improves the viability and growth of cells. It additionally contains L-Alanyl-L-Glutamine and therefore supplies a longer shelf life. Moreover, we manufacture several types of Leibovitz’s L-15 MAX based on your requirements.
Description
Background
Leibovitz’s L-15 Medium – MAX is one of the commonly used Media for Mammalian cell culture.
Advantages
The advantages of Leibovitz’s L-15 MAX over Leibovitz’s L-15 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. Therefore, one way to minimize L-glutamine degradation in media is to gradually add these amino acids to your cell culture. Unfortunately, maintaining a consistent level of L-glutamine by tracking time can be a tedious and potentially impossible task.
Alternatively, L-alanyl-L-glutamine can be used since 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 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
Leibovitz’s L-15 Medium – 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 Leibovitz’s L-15 MAX based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
- Phenol Red
Leibovitz’s L-15 MAX contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).
