Abstract From the Canadian patent

The presence or absence of a nucleic acid sequence of an isolate of HTLVI and/or HTLVII 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.
