Gibco™ ExpiCHO™ Expression System Kit DFS Item

Provides the highest protein yields possible in a transient CHO system

Manufacturer:  Gibco™ LSA29133

Catalog No. A29133

Includes: 2 vials frozen ExpiCHO-S™ cells, 1 bottle 1000mL ExpiCHO™ Expression Medium, 1 ExpiFectamine™ CHO transfection kit for 1 L of culture, 1 vial Antibody Expressing Positive Control Vector, 1 bottle 100mL OptiPRO™ SFM; store all components at +2° - +8° C, except frozen cells stored in liquid nitrogen



  • Milligram to multigram yields of recombinant protein per liter of culture in 5 to 14 days post-transfection, which are frequently higher than transient 293-based systems
  • Cost-effective transient expression in CHO cells, allowing scientists developing protein biotherapeutics to work with CHO-expressed proteins from start to finish in the drug development process
  • A robust alternative mammalian transient expression host, allowing for production of proteins that are difficult to express in HEK293 cells
  • Flexible, reliable culture and transfection protocols with multiple options that readily fit into current transient expression workflows
  • Scalable expression for cultures from <1 mL to >10 L, thus generating the amount of protein needed for your application
