CA 2402319

The present invention relates generally to oligonucleotide analogues that include novel protein nucleic acid molecules (PNAs), particularly monomers, dimers, oligomers thereof and methods of making and using these oligonucleotide analogues. The PNAs of the present invention are characterized as including a variety of classes of molecules, such as, for example, hydroxyproline peptide nucleic acids (HypNA) and serine peptide nucleic acids (SerNA). The invention includes monomers, homodimers, heterodimers, homopolymers and heteropolymers of these and other oligonucleotide analogues. The present invention includes method of using these oligonucleotide analogues in the detection and separating of nucleic acid molecules, including uses that include the utilization of oligonucleotide analogues on a solid support. The present invention also includes methods for purifying or separating nucleic acids by hybridization with the oligonucleotides of the present invention, such as mRNA molecules. The present invention also includes the use of oligonucleotides of the present invention in antisense and homologous recombination constructs and methods.

La présente invention concerne de manière générale des analogues d'oligonucléotides comportant des molécules d'acide nucléique d'une nouvelle protéine (PNA), notamment des monomères, dimères, oligomères de celles-ci et des procédés de production et d'utilisation de ces analogues d'oligonucléotides. Les PNA de la présente invention sont caractérisées en ce qu'elles comportent une variété de classes de molécules, telles que, par exemple, les acides nucléiques peptidiques hydroxyproline (HypNA) et les acides nucléiques peptidiques de sérine (SerNA). L'invention concerne également des monomères, homodimères, hétérodimères, homopolymères et hétéropolymères de celles-ci et d'autres analogues d'oligonucléotides. L'invention concerne en outre des procédés de mise en oeuvre de ces analogues d'oligonucléotides dans la détection et la séparation de molécules d'acides nucléiques, y compris des utilisations comportant la mise en oeuvre d'analogues d'oligonucléotides sur un support. La présente invention comprend également des procédés de purification et d'isolement d'acides nucléiques par hybridation avec les oligonucléotides de l'invention, telles les molécule ARNm. Enfin, la présente invention concerne l'utilisation des oligonucléotides de l'invention dans des constructions et des procédés de recombinaison d'homologues et d'antisens.
