Why is GlutaMAX Supplement (Cat. Nos. 35050061, 35050079) recommended over L-glutamine when reconstituting Geltrex Reduced Growth Factor Basement Membrane Matrix?

GlutaMAX Supplement (Cat. No. 35050061, 35050079) is highly recommended to reconstitute Geltrex Reduced Growth Factor Basement Membrane Matrix because it offers higher stability than L-glutamine. The L-glutamine in Geltrex matrix comes in the form of the dipeptide L-alanyl-L-glutamine, which degrades slower than L-glutamine in cell culture. While GlutaMAX supplement is highly recommended, it is not required for Geltrex matrix–based culture systems.

Does Dynamis AGT Medium (Cat. Nos. A2617501, A2617502, A2617503, A2617504) require supplementation for use?

When using Dynamis AGT Medium (Cat. Nos. A2617501, A2617502, A2617503, A2617504) for culturing a CHO cell line other than the glutamine synthetase (GS) gene expression system (GS-CHO expression system), the addition of 2-8 mM L-glutamine or a similar amount of GlutaMAX Supplement (Cat. No. 35050079, 35050061) is recommended.

Note: We recommend that you supplement with glucose as needed so that glucose levels don’t fall below 2g/L in culture (see the product User Guide for more details).

Do my cells need to adapt to GlutaMAX Supplement (Cat. No. 35050061, 35050079)?

Some cell lines may require an adaptation period, and the culture may lag in growth until it becomes accustomed to GlutaMAX Supplement (Cat. No. 3050061, 35050079). For serum-free media it is best to add L-glutamine along with GlutaMAX supplement. We don’t recommend that you use GlutaMAX supplement with insect cells such as Sf9.

Will depletion, absence, or breakdown of essential growth-promoting components such as glutamine or growth factors reduce the growth rate of my culture?

Yes. If you suspect that this is the case, remove the medium and add fresh medium. Alternatively, you can supplement medium with growth-promoting components. It is also possible to substitute GlutaMax I or II for glutamine in the medium to prevent glutamine exhaustion.

Will the media formulations containing GlutaMAX supplement change with respect to L-glutamine content?

In all media containing GlutaMAX supplement dipeptides as a substitute for L-glutamine, concentration is equimolar with the L-glutamine in the original formulation.
