questions

Find clear answers to common questions about Celltheon’s platforms, services, development workflows, timelines, and collaboration models.

Platforms & technologies

Celltheon’s protein expression services are built on OmniCHO™, our proprietary CHO-K1 transient expression system. OmniCHO™ delivers transient titers that rival or exceed what most platforms achieve only with stable cell lines—averaging 1.5 g/L for mAbs and regularly exceeding 3 g/L.
