Cytotoxicity index
WebCytotoxicity tests use a series of increasing concentrations of the antiviral product to determine what concentration results in the death of 50 percent of the host cells. This value is the median cellular cytotoxicity concentration and is identified by the 50% cytotoxic concentration (CC50). WebCytotoxicity Index was calculated by dividing the total red object area (mm 2 /well) of all time points by the value at time=0. For the spheroid assay, NucR-expressing PLC/PRF/5 …

Cytotoxicity can also be measured by the sulforhodamine B (SRB) assay, WST assay and clonogenic assay. Suitable assays can be combined and performed sequentially on the same cells in order to reduce assay-specific false positive or false negative results. See more Cytotoxicity is the quality of being toxic to cells. Examples of toxic agents are an immune cell or some types of venom, e.g. from the puff adder (Bitis arietans) or brown recluse spider (Loxosceles reclusa).
