PNA and LNA throw light on DNA.
In some aspects, homogeneous (all-in-solution) nucleic acid hybridization assays are superior to the traditionally used heterogeneous (solution-to-surface) alternatives. Profluorescent probes, which reveal fluorescence enhancement or fluorescence polarization upon their binding to DNA and RNA targets, are a paradigm for the real-time sequence-specific homogeneous detection of nucleic acids. A variety of such DNA or RNA-derived probes of different constructs has already been developed with numerous applications. However, the recent additions to the field - locked nucleic acids (LNAs) and peptide nucleic acids (PNAs) - significantly increase the potential of profluorescent probes and provide a robust impulse for their new uses.
