Power to start process development faster
As a fortified medium, Dynamis™ AGT™ provides the power to get to a high cell density over 10 million cells per mL faster than competitive products and sustains that cell density longer by just maintaining glucose levels. The viable cell growth achieved make it a good choice for scale-up if you have started with CD FortiCHO™ medium. When paired with EfficientFeed™ C+ AGT™ Supplement, it provides a fast and efficient way to develop a process.

The power to streamline transfer to manufacturing
By choosing Dynamis™ AGT™ Medium, you obtain not only the benefits of the medium formulation, but also the benefits of AGT™ dry format technology. This all-in-one product is designed to simplify scale-up and manufacturing by being easy to reconstitute (just add water), with no adjustments of pH or osmolarity necessary.

Cells adapted to other commercially available serum-free media can be subcultured directly into Gibco® FreeStyle™ CHO Expression Medium, usually without any further adaptation. Cells usually require adaptation from serum-containing formulations. Cells cultured in Gibco® FreeStyle™ CHO Expression Medium can be transfected using lipid-based transfection reagents, such as Freestyle™ MAX reagent.

Animal origin–free, protein-free and chemically defined formulation
Gibco® FreeStyle™ CHO Expression Medium is animal origin–free, protein-free, and chemically defined, allowing for easier purification of your protein of interest. Gibco® chemically defined media contain no proteins, hydrolysates, or components of unknown composition.

Easy use as part of the FreeStyle™ MAX CHO Expression System for protein production
The FreeStyle™ MAX CHO Expression System is a breakthrough technology for rapid (see figure) and high-yield mammalian protein production in 30 mL and 1 L batch sizes (see figure). The FreeStyle™ MAX CHO Expression System combines GIBCO® FreeStyle™ media, FreeStyle™ MAX reagent, and either FreeStyle™ CHO-S cells or FreeStyle™ 293-F cells in one kit.

Scalability in spinner flasks and bioreactors
Protein production using Gibco® FreeStyle™ CHO Expression Medium can be scaled up in spinner flasks or bioreactors.
