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.

Why did my 200 mM L-glutamine precipitate when I thawed it?

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