3D InSight™ Antibody Penetration Assay Service | InSphero

Assess penetration of antibodies and engineered antibody fragments in vitro

Penetration and distribution of biologics can depend on a variety of factors, such as tissue density, antibody affinity, antigen density per cell and physico-chemical properties. 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.

Standard Protocol

  • Phase 1: Model Characterization assessment of model feasibility for antibody penetration assay using beta integrin antibody
  • Phase 2: Biologic Detection optimization of detection protocol for biologics of interest by immunofluorescence (IF)
  • Phase 3: Kinetic Penetration Assay assessment of antibody penetration kinetics over 3 time points
