Achieve 3 g/L protein yields in a transient CHO system

Switching from 293 to CHO cells during drug development may cost you precious time and create uncertainty. Now there's a better way. The new Gibco™ ExpiCHO™ Expression System provides the highest protein yields possible in a transient system. That means you can always work in CHO cells, starting from discovery.


What's in the system?

  • 2 vials of frozen ExpiCHO-S cells
  • 1 liter of ExpiCHO Expression Medium
  • 1 ExpiFectamine CHO Transfection Kit, sufficient to transfect 1 liter of culture
  • OptiPRO™ Serum-Free Medium
  • An Antibody-Expressing Positive Control Vector
