よくあるご質問(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.

'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.

'Real-time measurements of second messengers in living cells, such as cAMP, are usually performed by ratiometric fluorescence resonance energy transfer (FRET) imaging.

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
