8 个常见问题解答

清除，缺少或降解谷氨酰胺或生长因子等促生长的基本成份会对培养物的生长速率造成影响么？

是的。如果您怀疑发生了类似情况，请移去培养基并换用新的培养基。或者，您可以添加含有促生长成份的培养基。也可使用I或II型GlutaMAX取代培养基中的谷氨酰胺，以避免谷氨酰胺被耗竭。

配方中含有Gibco GlutaMAX添加剂会改变L-谷氨酰胺的含量么？

在所有以GlutaMAX双肽添加剂作为L-谷氨酰胺替代品的培养基中，谷氨酰胺的浓度都与原始配方中的L-谷氨酰胺浓度处于同等的摩尔水平。

Is there any other difference between Opti-MEM I Reduced Serum Medium and Opti-MEM I Reduced Serum Medium, no phenol red besides the presence/absence of phenol red?

I noticed that Opti-MEM I Reduced Serum Medium does not contain any serum. Why do you then refer to it as "Reduced Serum Medium"?

Opti-MEM I Reduced Serum Medium is a serum-free medium. The reason why it is called “reduced-serum medium” is because you only need to supplement this medium with 1-5% FBS instead of the standard 10% FBS.

Opti-MEM I Reduced Serum Medium can be used as is (without serum) for transfection of cells. However, for long-term cell culture, you need to add serum to the medium to keep cells healthy.

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.
