General description

L-glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly. Optimal cell performance usually requires supplementation of the media with L-glutamine prior to use.

Lysine methylation of non-histone proteins has emerged as a key regulator of many cellular functions. Although less studied than other post-translational modifications such as phosphorylation and acetylation, the number of known methylated non-histone proteins is rapidly expanding. We have identified

Importance and uses of glutamine in hybridoma and mammalian cell culture

Human renal proximal tubule epithelial cells (RPTECs) are commonly used to predict human renal drug permeability and to investigate drug efflux. We have generated transporter knockout (KO) cell lines using CompoZr® Zinc Finger Nuclease (ZFN) technology in a proprietary renal proximal tubule epithelial cell line.

Questions

1–4 of 4 Questions  
  1. How much of Product G7513 should be used in cell culture media?

    1 answer
    1. In general, MEM typically contains 0.292 g/L L-Glutamine. A 200mM Glutamine solution is equivalent to 29.23 mg/mL. So it needs to be diluted around 100 times.

  2. Why is there a precipitate in the 200 mM L-glutamine solution, products G7513 and G2150, after thawing at room temperature?

    1 answer
    1. L-Glutamine, 200 mM solution, tends to precipitate in solution when chilled.  After thawing, it will be an opalescent solution.  If allowed to settle, there can be some crystalline insolubles at the bottom of the bottle.The product should be warmed to 37°C for complete solubilization.  To limit the number of times the product needs to be warmed to 37°C, the product can be divided into working aliquots which are stored at -20°C and used as needed.  This will expose the product to the minimal amount of warming cycles.

  3. Is the molecular weight of L-Glutamine 146.14 or 146.15? The label information changed.

    1 answer
    1. Based on a molecular formula of C5H10N2O3, the molecular weight to seven significant figures is 146.1456. Over the years, this value may have been reported in Sigma-Aldrich documentation or on labels as either 146.15 (by rounding up) or 146.14 (by truncation). The material itself has not changed.
