Facile functionalization of peptide nucleic acids (PNAs) for antisense and single nucleotide polymorphism detection

Abstract

In this report, we show how a convenient on-resin copper-click functionalization of azido-functionalized peptide nucleic acids (PNAs) allows various PNA-based detection strategies. Firstly, a thiazole orange (TO) clicked PNA probe facilitates a binary readout when combined with F/Q labeled DNA, giving increased sensitivity for antisense detection. Secondly, our TO-PNA conjugate also allows single nucleotide polymorphism detection. Since antisense detection is also possible in the absence of the TO label, our sensing platform based on azido-D-ornithine containing PNA even allows for additional and more advanced functionalization and sensing strategies.
