L(+)-Glutamine, powder cell culture reagent, Corning®
Supplier: Corning
Synonyms:
(S)-(+)-Glutamine
L-glutamine is an essential amino acid and a key component of culture media, serving as a major energy source for propagating cells. It is very stable as a dry powder and as a frozen solution but degrades rapidly in liquid media or stock solutions, producing toxic compounds. Optimal cell performance usually requires supplementation of the media with L-glutamine prior to use.
This product was tested in accordance with currently approved Mediatech, Inc. specifications and procedures. Testing procedures are maintained in compliance with the current versions of the USP and/or EP, where applicable.
