Several methods are used to measure cell viability: - Colorimetric Assays: These include the MTT, MTS, and XTT assays, which measure mitochondrial activity as an indicator of cell viability. - Fluorescent Assays: Such as the Calcein-AM assay, which utilizes fluorescent dyes to differentiate between live and dead cells. - Flow Cytometry: This technique uses fluorescent markers to analyze cell populations and viability. - Impedance-Based Assays: Real-time measurement of electrical impedance changes to determine cell viability.
