Gibco L-Glutamine is a ready-to-use amino acid supplement for cell culture. L-glutamine is an amino acid required in cell culture for the formation of purine and pyrimidine nucleotides, amino sugars, glutathione, L-glutamate, and other amino acids, as well as in protein synthesis and glucose production. Unlike most other amino acids, L-glutamine is not stable in solution with a rate of degradation dependent upon time, temperature, and pH. The optimal concentration depends upon the cell type and medium used to culture the cells, but generally falls in the range of 2–6 mM.

Gibco L-Glutamine supplement is a ready-to-use 200 mM stock solution for cell culture supplementation that supports of many critical cellular functions, including:

  • Formation of purine and pyrimidine nucleotides
  • Formation of amino sugars, glutathione, and L-glutamate
  • Formation of other amino acids
  • Protein synthesis
  • Glucose production

Frequently asked questions (FAQs)

Why did my 200 mM L-Glutamine precipitate out of solution when I thawed it?

When L-glutamine is in a concentrated stock solution it easily precipitates when cooled. Warming the solution briefly in a 37C water bath with gentle swirling will dissolve the precipitate. Do not use the product unless the precipitate is fully dissolved.

Why does L-Glutamine (200 mM) (Cat. No. 25050149, 25030081, 25030164) solution have “Product of Brazil” on the label?

L-Glutamine (200 mM) (Cat. No. 25050149, 25030081, 25030164) solution is made in the USA from a raw material glutamine powder manufactured in Brazil. The country of manufacture of a component that has been subjected to manufacturing or processing operations in more than one country is the last country in which the component has been “substantially transformed”. A “substantial transformation” occurs in a country when a product emerges from a manufacturing process with a name, character, or use different from that of the original material(s) subjected to that process.

Diluting, purifying, sorting, testing, packing, repacking, or affixing labels to a product in a country does not constitute a “substantial transformation” in that country, hence the label must bear the country of the original raw material origin.

My order of L-Glutamine (Cat. No. 25030081) arrived frozen. Is it stable?

If L-Glutamine is completely or partially frozen, it is still stable. It becomes unstable when stored for extended periods of time completely thawed, especially above 2-8 degrees C.

Find additional tips, troubleshooting help, and resources within our Cell Culture Support Center.

What is your recommended method for thawing L-Glutamine before adding to cell culture media?

We recommend thawing at 2-8 degrees C and then warming at 37 degrees C until the material goes into solution. Mix it as it warms up to spend minimal time at elevated temperatures before you aliquot it.

Abstract
Metabolism of 4 beta -hydroxycholesterol in humans.
Authors: Bodin Karl; Andersson Ulla; Rystedt Eva; Ellis Ewa; Norlin Maria; Pikuleva Irina; Eggertsen Gösta; Björkhem Ingemar; Diczfalusy Ulf;
Journal:J Biol Chem
PubMed ID:12077124
'One of the major oxysterols in the human circulation is 4 beta-hydroxycholesterol formed from cholesterol by the drug-metabolizing enzyme cytochrome P450 3A4. Deuterium-labeled 4 beta-hydroxycholesterol was injected into two healthy volunteers, and the apparent half-life was found to be 64 and 60 h, respectively. We have determined earlier the half-lives ... More

'Inhibition of transforming growth factor beta (TGFbeta) signaling by the Epstein-Barr virus Latent Membrane Protein 1 (LMP1) may account, at least in part, for the oncogenic activity of LMP1.

Authors:Friedrich U, Blom AM, Dahlbäck B, Villoutreix BO,
Journal:J Biol Chem
PubMed ID:11316800
'Human activated protein C (APC) is a key component of a natural anticoagulant system that regulates blood coagulation. In vivo, the catalytic activity of APC is regulated by two serpins, alpha1-antitrypsin and the protein C inhibitor (PCI), the inhibition by the latter being stimulated by heparin.
