US Patent 7141377 Process for discrimination of nucleic acid sequence variants

A process of detecting a target nucleic acid using labeled oligonucleotides 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.
