Why was L-Glutamine eliminated from many of your formulas?


L-Glutamine is easily hydrolyzed in liquid and by-products of hydrolysis can be toxic to the cell. Additionally, the necessary concentration of L-Glutamine may be compromised after a period of time. Since L-Glutamine is an essential amino acid, it is best for the end-users to supplement media with the recommended concentration of fresh L-Glutamine.
