Enzyme-Linked … Cytopathic effect or cytopathogenic effect (abbreviated CPE) refers to structural changes in host cells that are caused by viral invasion. The infecting virus causes lysis of the host cell or when the cell dies without lysis due to an inability to replicate. Both of these effects occur due to CPEs. If a virus causes these morphological changes in the host cell, it is said to be cytopathogenic. Common examples of CPE include rounding of the infected cell, fusion with adjacent cells to form photographic expressionsWebCytopathic effects can be assayed in varied ways. Plaque Reduction Neutralization Testing (PRNT) has long been considered the standard for viral assays, but other assays can be used to measured cell viability or cell death such as MTT, MTS or Trypan Blue (see sample protocols below). photographic fictions

WebImportance of the cytopathic effect in virology research In a typical CPE assay, a monolayer of cells is infected with a virus and then monitored over several days (or weeks) to track morphological changes. These changes emerge in distinct foci corresponding to sites of infection. 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.
