WebAssays to measure cellular proliferation, cell viability, and cytotoxicity are commonly used to monitor the response and health of cells in culture after treatment with various stimuli. The proper choice of an assay method depends on the number and type of cells used as well as the expected outcome. Webnumber of dead cells (cytotoxicity assay), the number of live cells (viability assay), the total number of cells, or the mechanism of cell death (e.g., apoptosis). Table 1 shows a comparison of Promega’s homogeneous cell-based assays and lists the measured parameters, sensitivity of detection, incubation time, and detection method.
