Product Introduction
Background
L-glutamine is an essential element in cell culture that is not only an energy source of the cells, but also an important substance involved in protein synthesis and nucleic acid metabolism. The deficiency of L-glutamine will lead to poor cell growth and even death. L-glutamine is unstable in solution and easy to degrade spontaneously, so it is necessary to supplement a certain amount of L-glutamine in culture medium to meet the needs of cell growth after a period of time or when cells grow badly.

FAQs
-
Q:1Why did my 200 mM L-glutamine precipitate when I thawed it?
AnswerWhen L-glutamine is in a concentrated stock solution it easily precipitates when cooled. Warming the solution briefly in a 37℃ water bath with gentle swirling will dissolve the precipitate. Do not use the product unless the precipitate is fully dissolved.
