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 quantitative method of measuring CPE with an … WebThe MTT assay was also applied to an unrelated virus, Sindbis, which is routinely titrated by plaque assay. MTT titration of Sindbis virus mutants was found to be valuable for preliminary screening. This assay can be adapted, by correlation to an accepted titration method, to any viral system which produces measurable cytopathic effect.

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 plates were then sealed and incubated at 250C for 14 days. Plates were observed daily for cytopathic effect (CPE). If CPE or toxicity was observed, blind passage assays were setup. If CPE was noted, steps were taken to identify the suspect virus. CPE was compared to virus controls provided by Auburn (SC95-02, LMBV4, 15 May 97).
