Synonym(s): (S)-2,5-Diamino-5-oxopentanoic acid; L-Glutamic acid 5-amide
Formula: H2NCOCH2CH2CH(NH2)CO2H
Formula Weight: 146.14
CAS No.: 56-85-9
Suitability: Qualified for use in cell culture applications, especially serum-free cell culture.
Other Notes: The dipeptide L-Ala-LGln is frequently used in modern serum-free media formulations because it provides a more stable form of glutamine in vitro.
Packaging: 50 mL amber serum vial with rubber stopper.
Beilstein Registry Number: 1723797
EC No.: 200-292-1
Melting Point: 185°C (dec.)(lit.)
Biochem/physiol Actions: L-Glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-Glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly. Optimal cell performance usually requires supplementation of the media with L-glutamine prior to use.
Reconstitution: Prepares a 200 mM solution when reconstituted to 10 mL with sterile water.
Empirical Formula (Hill Notation): C6H6O2 · C6H4O2
