ABSTRACT:
The present invention is directed to a process of detecting a target nucleic acid using labeled oligonucleotides. This process uses the 5' to 3' nuclease activity of a nucleic acid polymerase to cleave annealed labeled oligonucleotide from hybridized duplexes and release labeled oligonucleotide fragments for detection. This process is easily incorporated into a PCR amplification assay.
