Development of an RNA/RNA hybridization assay for the detection of the HAV CF53 strain.
A quick and sensitive dot-blot assay using non-radioactive labelled RNA probes was developed for the detection of the CF53 strain of hepatitis A virus (HAV) in cell culture. The cDNA of the 5' end of the HM175 strain was inserted in a transcription vector pSPT18 and was used to synthesize 32P- or digoxigenin-labelled RNA probes. These RNA probes specifically detected the RNA of the CF53 strain and can be used to detect HAV in PLC/PRF/5 cells. The sensitivity of non-radioactive tests was comparable to that of radiolabelled probes.
