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.<\/p>\n<p>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.<\/p>\n<p>In addition to our Max formulation products, we manufacture PurMa<sup>TM <\/sup>GluaSup (Cat# P3S210 559), a combination of L-alanyl-L-glutamine that prevents the degradation of L-glutamine.<\/p>\n<h2>Contents<\/h2>\n<h3>Basal Medium Eagle-MAX (BME-MAX) in Hanks\u2019 Buffer contains:<\/h3>\n<ul>\n<li>5 mM sodium pyruvate<\/li>\n<li>High glucose (4.5g\/L)<\/li>\n<li>Non-Essential Amino Acids<\/li>\n<li>3.7 g\/L Sodium Bicarbonate; PurMa Biologics Manufactures several types of Basal Medium Eagle-MAX (BME-MAX) in Hanks\u2019 Buffer based on the amount of Sodium Bicarbonate and HEPES (PH capacity)<\/li>\n<li>Phenol Red<\/li>\n<\/ul>\n<p>Basal Medium Eagle-MAX (BME-MAX) in Hanks\u2019 Buffer contains no proteins, lipids, or growth factors.
