WebOct 27, 1998 · Cell lysates were prepared following 2 days of puromycin selection (for noncytopathic replicons) or 18 h after infection at a moi of 10 (packaged cytopathic replicons). For the noncytopathic replicons, expression levels plateau after 2 days of selection; for the cytopathic replicons, 18 h precedes the onset of 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 … See more CPEs are important aspects of a viral infection in diagnostics.
