Prepare your CHO Cells For Higher Productivity By Optimizing Perfused Seed Train

The conventional seed train process is time-consuming and labor intensive. However, there is a solution for achieving higher cell densities: using perfused seed train with specially designed expansion cell culture medium.

Cellvento® 4CHO-X Expansion Medium has been developed for N-1 perfusion for CHO cell lines. It is formulated with a high nutrient concentration to achieve low cell specific perfusion rates (CSPRs) at high cell densities, and to support growth during the entire seed train.

• Achieve higher productivity in your production bioreactor
• Enable high seed inoculation of your production bioreactor through higher cell biomass
• Reduce your upstream footprint by decreasing the number of bioreactors in the seed train
• Save time by eliminating adaptation during transfers from the vial thaw to expansion and production - directly transfer to production bioreactor in our fed batch or perfusion media*.
