Abstract
The detection of hepatitis A virus (HAV) negative-strand RNA, which is synthesized during replication of the positive-strand RNA genome, proved to be difficult. We developed a method for the specific detection of HAV negative-strand RNA by RNA-DNA hybridization and luminescence detection using an anti-RNA:DNA hybrid antibody. This method, which is also applicable for the specific detection of positive-strand RNA, offers a simple, yet relatively rapid and certain means of detecting low amounts of RNA such as HAV negative-strand RNA. By using appropriate hybridization DNA probes, the method should be applicable for the detection of single-stranded RNA species of different viruses in general.
