    摘要: A novel class of compounds known as peptide nucleic acids, bind complementary DNA and RNA strands, and generally do so more strongly than the corresponding DNA or RNA strands while exhibiting increased sequence specificity and solubility. The peptide nucleic acids comprise ligands selected from a group consisting of naturally-occurring nucleobases and non-naturally-occurring nucleobases, including 2,6-diaminopurine, attached to a polyamide backbone, and contain alkyl amine side chains.

    摘要: Nucleic acid analogues such as peptide-nucleic acids (PNAs) which hybridize strongly to nucleic acids are used to inhibit nucleic acid amplification procedures such as PCR. False positives in subsequent PCR assays are prevented by hybridizing a PNA to PCR amplification products. Assays capable of discriminating between single base mutants are conducted by using a PNA hybridizing to one of the two allelic forms to inhibit a PCR amplification of that form selectively. Asymmetric PCR amplifications are carried out by starting a PCR symmetrically using like quantities of forward and reverse primers, and, once the amplification is established, disabling one primer by hybridizing a PNA thereto.
