WebCytopathic effect (CPE) inhibition assay. CPE is morphological changes in cells caused by cytopathogenic virus infection. CPE assay is used to evaluate test articles’ ability to inhibit CPE. This is the most cost-effective and time-efficient assay we offer for high throughput screening of overall antiviral activity. 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
