Does adding GlutaMAX-I improve the media quality as opposed to L-Glutamine at the same 4 mM concentration? Can GlutaMAX-I and L-Glutamine be used interchangeably?
We typically recommend the addition of L-Glutamine. GlutaMAX is the dipeptide form of Glutamine which allows for longer stability in culture. The L-Glutamine form is more readily available to the cells early in culture when it is most critical. However, customers use GlutaMAX interchangeably without any negative effects.
