DETAILS

Description (English)

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.

Description (简体中文)

Biochem/physiol Actions
L-谷氨酰胺是一种基本氨基酸，是作为细胞培养主要能源的培养基所必不可少的组成部分。L-谷氨酰胺干粉和冷冻溶液十分稳定。但液体培养基或储存液中的 L-谷氨酰胺分解相对较快。使用前，通常需要补充含·L-谷氨酰胺的培养基，以获得最佳细胞性能。
