Gibco® L-glutamine is an amino acid 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. L-Glutamine, unlike most other amino acids, is not stable in solution. The rate at which this degradation proceeds is a function of time, temperature and pH. Life Technologies also offers Gibco® GlutaMAX™ supplement as a stable alternative to L-glutamine.

Gibco® L-glutamine (non-sterile) powder should be made as a filter-sterilized stock solution of 200 mM (or similar) in distilled water. The optimal use concentration is dependent upon the cell type and medium used to culture the cells, but generally falls in the range of 2 – 6 mM.
