Cells assessed in 3D culture models frequently provide more physiologically relevant data than cells studied in standard 2D formats. Thus, there is a need for convenient and effective assays explicitly validated for 3D microtissues. Here we report on CellTiter-Glo® 3D, a bioluminescent ATP detection assay for measuring cell viability with an optimized protocol and an improved formulation that has been expressly designed to measure the viability of 3D microtissues. This single-component liquid reagent has significant lytic capacity, exhibits high ATP recovery, and can be used to measure the viability of microtissues grown in a variety of 3D culture models, including ECM-independent (e.g., hanging drop), ECM-dependent (e.g., Matrigel™), and synthetic scaffolds (e.g., Alvetex™).
