3D InSight™ Tumor Relapse, Chemoresistance Assay Service

Classify the kinetics of tumor relapse potential in vitro

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.

Characterization Data

Assess tumor relapse potential following removal of 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.
