Description
Glutamine XL is a chemically stable dipeptide useful as a cell culture media supplement as a replacement for unstable solutions of L-Glutamine.
- Stable L-Alanyl-L-Glutamine in physiological saline
Applications
Standard, unstabilized solutions of L-glutamine spontaneously break down over time to release cytotoxic amines. Glutamine XL is a stabilized solution that prevents degradation and cytotoxicity, with the benefit of a long shelf life.
The incorporated L-alanine protects the unstable alpha amino acid group of L-glutamine. Aminopeptidase within the cells cleaves the dipeptide, gradually releasing both L-glutamine and L- alanine for use by the cell.
Recommendation
Dilute Glutamine XL the same way as L-glutamine in the appropriate cell culture medium. Typically, L-glutamine is diluted to concentration of 1-4mM. Protect from light.
