ChemStress® Clone Robustness Applications

ChemStress® Clone Robustness Study


  • Selection of the best clone candidates is a significant and critical step to ensuring optimal performance in biomanufacturing 
  • Standard cell viability and titer measurements are not fully reflective of real bioprocessing environments



ChemStress®  empowers the selection of only the most robust clones by analyzing cell functional responses to a panel of 21 small chemical molecules, challenging key production pathways, and mimicking recurrent bioprocess stresses cells are likely to experience in production.

By applying the ChemStress® Robustness technology, it is possible to drive clone selection with rich functional performance information and advanced data analysis. The ChemStress® robustness ranking offers an innovative and actionable index to streamline your clone selection and maximize the production value of your process.
