L-Glutamine is an amino acid that is required for cell culture. L-Glutamine participates in the formation of purine and pyrimidine nucleotides, amino sugars, glutathione, L-glutamate, and other amino acids, as well as in protein synthesis and glucose production. Unlike most other amino acids, L-glutamine is not stable in solution. The rate at which degradation proceeds is a function of time, temperature, and pH. Gibco™ L-glutamine is a ready-to-use 200 mM stock solution that acts as a cell culture supplement. The optimal concentration is dependent upon the cell type and medium used to culture the cells, but generally falls in the range of 2–6 mM.

We also offer GlutaMAX™ Supplement as a stable alternative to L-glutamine.
