Introduction to Interferon Alpha Cytopathic Effect Assay

WebThis assay can be used to detect the antiviral activity of the test drug and cytopathicity can be expressed microscopically as 0 = No CPE; 1 = 0–25%; 2 = 25–50%; 3 = 50–75%; 4 = 75–100%. This initial evaluation is usually done at a twofold concentration (with a 10-fold difference, e.g., 1 and 10 ng/ml or μg/ml). 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.

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 WebThe Viral ToxGlo™ Assay is a simple “add-mix-measure” homogeneous assay for monitoring viral-induced cytopathic effect. It offers a highly sensitive, precise and …
