Cytotoxicity level
WebWhat is a cytotoxicity assay? Toxicity of exogenous physical, biological, or chemical agents can be investigated on an organ- or whole-body level during animal experiments [1]. However, these experiments come with numerous ethical objections and lack the possibility to investigate human cells [1-3]. Therefore, in vitro cytotoxicity experiments are … WebHere we introduce cytotoxicity assays that assess the presence of dead cells by detecting outflux of certain proteins (dead-cell protease, lactate dehydrogenase) or influx of chemicals (DNA dye). Dead-cell Protease …
