3D InSight™ Tumor Microtissues is an ideal tool for oncology drug discovery, owing to their 3-dimensional spheroidal shape, tumor and stromal-cell-type components, and native-like extracellular matrix (ECM) protein composition.

They are a proven, robust method for assessing the penetration of antibodies and engineered antibody fragments in vitro (1,2). They can also be used for assessing the effectiveness of therapeutics designed to prevent tumor relapse.
