| 摘要 |
The present invention is directed to methods of generating a signal indicative of the presence of said target nucleic acid sequence in a sample, comprising, incubating a sample comprising a an amplified target nucleic acid and a nucleic acid polymerase which substantially lacks 5′ to 3′ exonuclease activity, adding a thermostable fen nuclease consisting of 5′ to 3′ exonuclease and/or endonuclease activity so as to cleave a cleavage structure and generate a signal.
