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.

Preparation Note

Prepared in cell culture grade water.

Application

L-glutamine is an essential amino acid that is a crucial component of culture media, which serves as a major energy source for cells in culture. Optimal cell performance usually requires supplementation of the medium with L-glutamine prior to use.

Subculture of Semi-Adherent Cell Lines

Some cultures grow as a mixed population (e.g. B95-8 - marmoset) where a proportion of cells do not attach to the tissue culture fl ask and remain in suspension. Therefore to maintain this heterogene...
