ChemStress®

ChemStress® is ValitaCell’s innovative technology used to improve your process analytics

ChemStress® technology allows cells and media functional characterization by mimicking bioprocessing stressful conditions in a SMALL-SCALE model & EARLY in the process. Combining ChemStress® biological relevant outputs with advanced analytics, we support our customers to achieve the highest level of bioprocess performance.

Biologics & Cell Therapy Applications

ChemStress® technology enables both clone & media robustness testing in a small-scale system, early in the process, and in an efficient & data-rich way.

Incubate your cells and/or media with the ChemStress® 96-well plate chemicals and simply use a standard plate reader to measure cell viability and titer in a small-scale simulated production bioreactor environment.

ValitaCell’s R&D team is currently working on the development of the first innovative characterization assay for primary cells and media in the cell therapy space.

Principle of ChemStress® Technology

Clone & Media quality and robustness assessment enabled by ChemStress® allows you to look far beyond the standard quality assurance analytics that relies only on cell viability and titer measurements.

Validate the robustness of your media, select your best media formulation and profile your clones by assessing deep cell functional activity under stressful conditions mimicking known bioprocess stresses and challenging key metabolic pathways in a small-scale model and early in the process.

Cells are challenged with a panel of selected categories of 21 small molecule chemicals challenging key production pathways and mimicking recurrent bioprocess stresses cells are likely to experience in production.

ChemStress® Applicability

Media and clone routine testing and characterization is critical during Cell Line Development, through Process Scale-Up and Optimization, and especially before starting and during Manufacturing. ChemStress® can be flexibly integrated into your standard QC testing at any stage providing more confidence to bring forward a specific media lot, the most robust media formulation, or your best clones.
