title: Immunofluorescent detection of double-stranded RNA in cells infected with reovirus, infectious pancreatic necrosis virus, and infectious bursal disease virus.
abstract: Urea treatment of ethanol-fixed virus-infected cells exposed nucleic acid antigens for immunofluorescence. Three double-stranded (ds) RNA-containing viruses showed bright fluorescence using antibodies against dsRNA. Three single-stranded RNA-containing viruses showed less intense fluorescence with anti-dsRNA. Four out of five cell lines persistently infected with various RNA-containing viruses showed no dsRNA detectable by immunofluorescence.
