Cellvento® 4CHO-X Brochure

There are several advantages to using perfusion in your seed train, namely, flexibility in your production processes, increase in capacity, and footprint reduction.

Reducing the number of bioreactors in your seed train leads to better utilization and eliminates traditional bottlenecks (compressed seed train). Additionally, using N-1 perfusion enables the inoculation of a production bioreactor with higher cell densities for high seed production process formats.

Cellvento® 4CHO-X Expansion Medium has been specifically developed for N-1 perfusion for Chinese Hamster Ovary (CHO) cell lines. It is formulated with a high nutrient concentration to achieve low cell-specific perfusion rates (CSPRs) at high cell densities. The medium is chemically defined, of non-animal origin, and contains no hydrolysates or components of unknown composition.
