A ribonuclease-dependent cleavable beacon primer triggering DNA amplification for single nucleotide mutation detection with ultrahigh sensitivity and selectivity.

We described a ribonuclease-dependent cleavable beacon primer, an energy-transfer-tagged oligonucleotide inserted with a ribonucleotide, which can be cleaved by ribonuclease to generate enhanced fluorescence signals and initiate DNA amplification for single nucleotide mutation detection with ultrahigh sensitivity and selectivity.
