Dual-labeled PNA molecular beacons have been extensively used on their own or in combination with fluorescence melting curve analyses for genotyping [71][72][73] and analyses of genetic mutations, including single

Examples of fluorogenic non-ligated templated reactions are summarized in Table 2. Many of these reactions feature
