CHO4Tx®

CHO 4Tx® is a unique CHO transfection system developed by ExcellGene, a Swiss industry leader in complex recombinant protein expression in CHO cells, and the fruit of over two decades of experience as a contract development and manufacturing organization specialized in challenging protein expression services. CHO 4Tx® is dedicated to the discovery and preclinical research steps for new diagnostics or drug development processes, when large numbers of protein variants are needed in small amounts (from mg to g scale) to perform fast and efficient screening programs.

Your Advantages

CHO 4Tx® is designed to make protein 
expression in CHO cells easy, efficient and cost-effective

Easy

  • Our kits are ready-to-use and contain the exact volumes of media you’ll need to make your transfection
  • Our optimized protocol has only 3 steps with a dedicated medium for each step 
  • There is no need to wait for DNA complex formation 

Efficient 

  • Up to 7-fold higher titer vs. the industry reference (with standard protocol on IgG)
  • High purity supernatants are obtained, leading to easier and faster purification processes
  • Several protein variants can be produced in parallel

Cost-effective 

  •  High yields drastically reduce the cost per produced mg
  • Very competitive prices are applied, which include personalized technical support
  • Volumes of media are optimized for a zero waste use
