L-GLUTAMINE (5-13C) is a labelled gluamine. L-GLUTAMINE (5-13C) 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 (5-13C) is very stable as a dry powder and as afrozen solution. In liquid media or stock solutions, however, L-GLUTAMINE (5-13C) degrades relatively rapidly. Optimal cell performance usually requires supplementation of the media with L-GLUTAMINE (5-13C) prior to use.

L-Glutamine (5-13c, 99%) is a useful isotopic labeled intermediate for organic synthesis and other chemical processes.
