Use our Tumor Relapse Assay to classify the kinetics of cancer relapse potential in vitro
Leverage InSphero's tumor relapse assay to simultaneously determine the response of a tumor to your drug as well as the kinetics of tumor re-growth (relapse) following removal of the drug in vitro.
We use phenotypic (size-based) assessment of spheroid growth by bright-field imaging to allow continuous, non-lytic monitoring of spheroid growth over time through our advanced tumor relapse assay.
Tumor Relapse Assay Characterization Data
InSphero tumor relapse assay: assess cancer recurrent potential following removal of the drug in vitro.
Example tumor relapse kinetics for Doxorubicin showing recovery of HCT-116 tumor spheroid growth following single treatment (pulsed-green line) at the EC50 dose, compared to repeat-dosing over 10 days at the max response dose (gray line) or vehicle control (black line). Growth constants are used to determine relapse classification values at EC20 and EC50 values.
