Patent

CA 2414329

This invention is related to the immobilization of peptide nucleic acids (PNAs) onto solid surfaces for use in hybridization, purification, biosensing, and other biochemical applications. Specifically, their use to increase the thermal stability, specificity, and lifetime of devices based on in situ hybridization is disclosed. A method is disclosed by which peptide nucleic acids replace oligonucleotides as probes in the detection of specific DNA and RNA sequences.

La présente invention concerne l'immobilisation de protéines PNA sur des surfaces solides en vue d'être utilisées pour l'hybridation, la purification, la biodétection, et pour d'autres applications biochimiques. Plus particulièrement, cette invention concerne leur utilisation pour augmenter la stabilité thermique, la spécificité, et la duré de vie des dispositifs basés sur l'hybridation in situ. En outre, cette invention concerne un procédé au moyen duquel des protéines PNA remplacent les oligonucléotides comme sondes dans la détection de séquences d'ADN et d'ARN spécifiques.
