Multiplexed analysis of the three endonuclease, Nt.BbvCI, EcoRI, and HindIII by the DNA tetrahedron
module shown in Scheme 2. Panel I: sensing of EcoRI and HindIII, switches on the fluorescence of ROX and Cy5. Panel II: sensing
Nt.BbvCI and EcoRI by the sensing module, switches
on the fluorescence of FAM and ROX. Panel III: sensing Nt.BbvCI and HindIII by the sensing module, switches on the fluorescence
of FAM and Cy5. Panel IV: multiplexed sensing of all three endonucleases:
Nt.BbvCI, EcoRI, and HindIII, switches
on the fluorescence of FAM, ROX, and Cy5. In all experiments, the
concentrations of Nt.BbvCI, EcoRI, and HindIII corresponded to 0.2, 0.2, and 2 U μL–1, respectively.
