3D InSight™ Cancer Drug Efficacy Testing Service

Biochemical and phenotypic assessment of drug potency and efficacy using 3D tumor models

  • Assess four test compounds in 3D InSight™ Tumor Microtissues (monoculture or co-culture)
  • Utilize a repeat-dosing regimen over 10 day exposure period with kinetic-size profiling (spheroid area) and viability (Promega CellTiter-Glo®) endpoints
  • Receive potency (EC50) and efficacy (maximum response) values and growth constants for your compounds and 4 controls (Staurosporine, MEK162, Ipatasertib, Sorafenib/Sunitinib)
  • Compare results of test compounds to historical reference compound data set

  • Benchmark the efficacy of your drug in biologically relevant 3D tumor models

    Accelerate and increase your chances of discovering more effective drugs using organotypic multicellular tumor microtissues. We test your compounds or biologics of interest to assess their potency (EC50) and efficacy (maximum response) on tumor microtissues using 3D-optimized biochemical (ATP) and phenotypic (size) endpoints.

    • Test four compounds plus controls (Staurosporine, MEK162, Ipatasertib, Sorafenib/Sunitinib, DMSO)
    • 11 point dose-response curve, duplicate data points
    • 10 day exposure with dosing at day 0, 3, and 7
