Cytopathic effect assay protocol
WebPlaque assay . Plaque assay of a tissue culture-adapted viral strain. ... When applying this calculation, remember that the estimated mean will only be valid if the changes in the protocol required to visualize plaques do not alter viral expression as compared to conditions used to determine TCID 50. ... Cytopathic effect (CPE). WebIn this assay, viral infection kills host cells, and the cell viability is used as a surrogate readout for viral infection and replication. In other words, compounds with anti-viral activities rescue cells from the cytopathic effect of SARS-CoV-2 (a gain-of-signal assay).
