Description

Background

McCoy’s 5A Modified Media MAX (M5AMM-MAX) is a commonly used media for Mammalian cell culture.

Advantages

The advantages of McCoy’s 5A MAX over McCoy’s 5A  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, 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

McCoy’s 5A Modified Media MAX (M5AMM-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 McCoy’s 5A  based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
  • Phenol Red

McCoy’s 5A MAX contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).

    Review: I have worked directly with PurMa biologics on a number of projects ongoing in my lab. I find the media and the specialty Lipid Depleted Serum to be high quality and very consistent among batches, which is critical to our adipogenesis projects using primary stem cells. Also, the service from PurMa is outstanding for my lab.

    Review: I started my lab using the regular Gibco media components. We have shifted to Purma past 6 months and see no difference in the quality of our cell culture. Simply saying that Purma is cheaper, quicker to deliver and as good as Gibco. The best part was that Purma customized several media for our fish cell lines which was really helpful. Lastly, Seif walked through the customization of media over Zoom, that gave a lot of confidence for using those media solutions.

    Review: Reliable and dependable products. We purchased lipid-depleted FBS (LD-FBS) from PurMa Biologics and it worked great. We cross-checked the lipid content in the serum by GC-MS and Triglyceride assay and as advertised, did not find any lipids in the FBS.
