  • Detection of viruses by amplification and hybridization
    Patent number: 5176995
    Abstract: The presence or absence of a nucleic acid sequence associated with one or more related viruses in a sample containing one or more nucleic acids and suspected of containing such sequence can be detected by amplifying the sequence using primers to form extension products as templates and detecting the amplified product if it is present. This may be accomplished by adding a labeled hybridization probe to the amplified product either free in solution or after immobilization on a solid support. Preferably the virus constitutes AIDs viruses and hepadnaviruses.
