The CHO Toolkit: Flexible Solutions For Complex Molecules

Biologics are rarely one-size-fits-all, especially when it comes to complex or hard-to-express proteins. Sartorius addresses this challenge with a CHO Cell Line Development Service built on a modular toolbox approach. This flexible platform combines proprietary host cell lines, optimized expression vectors, predictive modeling, and high-throughput automation to tailor development strategies to each molecule’s unique needs. But the value doesn’t stop at early development. As Suzan Dexter, CTO of Sonnet BioTherapeutics, highlights, Sartorius’ adaptability and expert support are equally critical during scale-up for commercial manufacturing. With integrated mini-pool screening, CellCelector™-based single-cell cloning, and process intensification, the platform helps reduce risk, compress timelines, and deliver high-titer production—achieving research cell bank readiness in just nine weeks.

For teams facing tight deadlines or preparing for large-scale production, discover how this approach offers a streamlined, scalable path to success.
