L-Glutamin ist eine für Zellkulturen erforderliche Aminosäure. L-Glutamin ist an der Bildung von Purin- und Pyrimidin-Nukleotiden, Aminozuckern, Glutathion, L-Glutamat und anderen Aminosäuren sowie an der Protein-Synthese und Glukose-Produktion beteiligt. Im Gegensatz zu den meisten anderen Aminosäuren ist L-Glutamin in der Lösung nicht stabil. Die Geschwindigkeit des Abbaus verläuft in Abhängigkeit von Zeit, Temperatur und pH-Wert. Gibco™ L-Glutamin ist eine gebrauchsfertige, als Zellkulturergänzung fungierende 200 mM-Stammlösung. Die optimale Konzentration hängt von der Zellart und dem für die Zellkultur verwendeten Medium ab, liegt aber im Allgemeinen im Bereich von 2 – 6 mM.

Darüber hinaus bieten wir Gibco™ GlutaMAX™ Supplement als stabile Alternative zu L-Glutamin an.

Häufig gestellte Fragen (FAQ)

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.

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
Structural and energetic characteristics of the heparin-binding site in antithrombotic protein C.
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. We have identified a ... More

'Real-time measurements of second messengers in living cells, such as cAMP, are usually performed by ratiometric fluorescence resonance energy transfer (FRET) imaging. However, correct calibration of FRET ratios, accurate calculations of absolute cAMP levels and actual permeabilities of different cAMP analogs have been challenging. Here we present a protocol that ... More

'The pore-forming toxin streptolysin O (SLO) can be used to reversibly permeabilize adherent and nonadherent cells, allowing delivery of molecules with up to 100 kDa mass to the cytosol. Using FITC-labeled albumin, 10(5)-10(6) molecules were estimated to be entrapped per cell. Repair of toxin lesions depended on Ca(2+)-calmodulin and on ... More
Fabrication of synthetic polymer coatings and their use in feeder-free culture of human embryonic stem cells.
Authors:Nandivada H, Villa-Diaz LG, O'Shea KS, Smith GD, Krebsbach PH, Lahann J,
Journal:Nat Protoc
PubMed ID:21720316
The culture of human embryonic stem (hES) cells in defined and xenogeneic-free conditions will contribute substantially to future biotechnological and medical applications. To achieve this goal, we developed the first fully defined synthetic polymer coating poly[2-(methacryloyloxy)ethyl dimethyl-(3-sulfopropyl)ammonium hydroxide] (PMEDSAH) that sustains long-term growth of hES cells in different culture media. ... More
