ChemStress® Media Robustness Applications

ChemStress® Media Robustness Study


  • Standard Media QC and selection is a time consuming and costly process, that delivers limited biological information
  • Selection of the best media formulation during development, and screening for the most suitable lot of media for manufacturing, are both critical steps to maximize performance in biomanufacturing.



ChemStress® empowers the selection of only the most robust media formulations by analyzing the ability of a media to support cell growth and titer when key production pathways of the cells are challenged with a panel of 21 small chemical molecules, mimicking recurrent bioprocess stresses cells are likely to experience in production.

By applying the ChemStress® Robustness technology, it is possible to drive media selection, validate the stability of a media of choice &/or improve the performance of your media with rich functional performance information and advanced data analysis. The ChemStress® robustness ranking offers an innovative and actionable index to streamline your media selection and maximize the production value of your process.
