A label-free, impedance-based real time assay to identify drug-induced toxicities and differentiate cytostatic from cytotoxic effects

► A novel impedance based real-time cytotoxicity assay has been established. ► An analysis algorithm for impedance data has been developed. ► Cytotoxic and cytostatic compound effects could be distinguished. ► Results correlate well with corresponding in vivo data of the compounds.
