Peptide nucleic acid probes with charged photocleavable mass markers: Towards PNA-based MALDI-TOF MS genetic analysis.

Abstract:
Halogen-labelled peptide organic acid (HPOA) monomers have been synthesised and incorporated into sequence-specific peptide nucleic acid (PNA) probes. Three different types of probe have been prepared; the unmodified PNA probe, the PNA probe with a mass marker, and the PNA probe with photocleavable mass marker. All three types of probe have been used in model studies to develop a mass spectrometry-based hybridisation assay for detection of point mutations in DNA.
