Since their invention in 1991, peptide nucleic acids (PNAs) have been used in a myriad of chemical and biological assays. More recently, peptide nucleic acids have also been demonstrated to hold great potential as therapeutic agents because of their physiological stability, affinity for target nucleic acids, and versatility. While recent modifications in their design have further improved their...
Background & Objectives: Antisense peptide nucleic acids (PNA) that target growth essential genes show potent bactericidal properties without cell lysis. We considered the possibility that whether PNA treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to Dendritic cells (DCs). DCs are the most potent antigen presenting cells in the i...
BACKGROUND Nucleic acids detection using microarrays requires labelling of target nucleic acids with fluorophores or other reporter molecules prior to hybridization. RESULTS Using surface-bound peptide nucleic acids (PNA) probes and soluble fluorescent cationic polythiophenes, we show a simple and sensitive electrostatic approach to detect and identify unlabelled target nucleic acid on microa...
