ProCHO Protein-free CHO Media

  • Protein-free and serum-free media
  • Optimized for recombinant protein production by CHO cells
  • Free of animal-origin components
  • Available in 3 types

ProCHO protein-free CHO media facilitate the production and downstream processing of recombinant proteins expressed by CHO cells. The protein-free media support high-density cultures without the need for components of animal origin. ProCHO media contain very low levels of recombinant insulin.

Protein-free media types

Depending on your demands you can select one of the following media:

  • ProCHO™4: Enables concurrent transition of adherent CHO cells to serum-free culture in suspension. A key benefit is faster doubling times. With 0.1% Pluronic® F-68, without L-glutamine, hypoxanthine, or thymidine. Phenol red is optional.
  • ProCHO™5: Obtain higher protein yield with CHO cells already growing in suspension. It contains 0.1% Pluronic® F-68, but does not contain L-glutamine, phenol red, hypoxanthine, or thymidine.
  • ProCHO™AT: For adherent culture of CHO cells. Contains L-glutamine. Does not contain hypoxanthine or thymidine.
