WebAt the end of the exposure, the Viral ToxGlo assay was used to measure ATP, which serves as an indicator of cell viability. The TCID 50 or 50% cytopathic effect (CPE) is the virus dilution that reduces the measured cell viability by 50%. This value was used for subsequent studies on the potency of antiviral agents. direct proportion higherWebHemadsorption can be used to demonstrate infection with noncytopathogenic as well as cytocidal viruses, and can be demonstrated very early, e.g., after 24 hours, when only a small number of cells in the culture are infected. Hemagglutination is a different, though related phenomenon, in which erythrocytes are agglutinated by free virus (see below). fossetes lorealsWebFeb 9, 2011 · A cell-based assay utilizing cytopathic endpoints (CPE) was set up using Vero E6 cells to screen these antiviral compounds.
