Contributes to high proliferation efficiency and high survival rate, thereby increasing the cell quantity for cryopreservation or seeding in another reactor!
The "Cellvento 4CHO-X Expansion Medium" has been specially developed for N-1 perfusion of Chinese hamster ovary (CHO) cell lines. It contains high concentrations of nutrients to achieve high cell density at a low CSPR (Cell Specific Perfusion Rate: the amount of medium supplied per cell). It is chemically defined, free from animal-derived components, and does not contain any undefined components such as hydrolysates. 【Features】 ■ Specially formulated to control the metabolic profile of cells ■ Minimizes toxic by-products ■ Ensures appropriate nutrient levels for high cell density ■ Prevents nutrient depletion, improving the robustness and predictability of the seed train process ■ Usable in all expansion steps of the seed train, including N-1 ■ Achieves robust proliferation at low CSPR *For more details, please download the PDF or feel free to contact us.
