We offer an extensive line of assays and reagents for determining cell viability and cytotoxicity in monolayer cell cultures, 3D microtissues, primary cells, stem cells, bacterial cultures and virus-infected cells. Many Promega cell viability and cytotoxicity assays can be multiplexed with apoptosis and other assays to determine mechanism of cell death and sensitively compare data from well-to well, plate-to-plate and day-to-day.

Cell viability and cytotoxicity assays are based on colorimetric, fluorometric and bioluminescent detection chemistries. Real-time, live-cell assays repeatedly monitor over time and generate multiple data points from a single assay well. Endpoint assays can provide sensitive, high-throughput-amenable assay formats for determining cell health.
