ExcellGene

ExcellGene is a Swiss CDMO developing cell lines and bioprocesses for novel biologics and biosimilars. We build high-performing CHO and HEK293 cell lines (5–14 g/L) for any format — mAbs, bispecifics, Fc-fusions, viral proteins — through full process development, scale-up to 250 L, and GMP cell banking.

For biosimilars, license one of our 20+ ready-to-use cell lines or engage us for the molecule of your choice. Either way: a locked, transferable process and GMP Master Cell Bank, ready for manufacturing. 

Innovating in mammalian protein expression since 2001. From discovery to manufacturing.
