Cell Viability and Cytotoxicity Assays

We offer an extensive line of effective and innovative assays and reagents for determining cell viability and cytotoxicity. Choose from assays to measure viability in cell culture, 3D microtissues, bacterial cultures and virus-infected cells. Many can be multiplexed with apoptosis and other viability assays to determine mechanisms of cell death and sensitively compare data from well-to well, plate-to-plate, and day-to-day.
