Cytotoxicity assay testing
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. WebApr 1, 2024 · Cytotoxicity is the most common test category utilized in ensuring the safety of medical devices. Used as an important screening tool as well as a significant biological endpoint for submission requirements, these tests assess the cytotoxic potential of a device or material to inhibit cell growth or cause cell death.
