3D InSight™ Antibody Penetration Assay Service | InSphero

Assess penetration of biologicals and ADCs in 3D InSight™ Tumor Microtissues

Penetration and distribution of biologics can depend on a variety of factors, such as tissue density, antibody affinity, antigen density per cell and the physico-chemical properties of the biologic. The spherical, 3D structure and more native ECM and biology of 3D InSight™ Tumor Microtissues makes them ideal for assessing penetration of antibodies and engineered antibody fragments in vitro.

  • Test kinetics of antibody/ADC penetration and distribution in biomimetic 3D tumor models with native-like ECM and tissue density
  • Utilize immunohistochemical detection techniques to visualize the distribution of your biologic in the tumor tissue
  • Receive model suitability assessment, detection method detail, and penetration kinetic report
  • Optimize biological targeting and efficacy by comparing multiple constructs (e.g., full-length IgG, IgG Fc, sFv, bi-specific)
