    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.

    摘要: Binary probe and clamp compositions conduct methods for target hybridization detection. Where the probe is a substrate for exonuclease cleavage, the composition provides quantitation and detection of PCR products, by real-time and end-point measurements. Where the probe is an amplification primer, the composition provides an improved method for labelling and detection of PCR products. Probes and clamps may be labelled with fluorescent dyes, quenchers, hybridization-stabilizing moieties, chemiluminescent dyes, and affinity ligands. Clamps may be nucleic acid analogs, such as 2-aminoethylglycine PNA.

    摘要: A method is disclosed for preparing novel PNA synthons having protecting groups capable of removal under mild conditions. The PNA synthons are prepared by coupling novel N-substituted nucleobase intermediates having carbamate protection of the exocyclic amino group of the heterocycle to an amino protected backbone or an amino protected backbone ester of the amino acid N-(2-aminoethyl)-glycine. By the method of this invention, the resultant PNA synthons can have orthogonal protection of the carbamate protected nucleobase and the amino protected backbone. The PNA synthons are useful in the synthesis of peptide nucleic acids (PNAs) and other oligomers such as PNA-DNA chimeras, and may be used in automated synthesizers. Novel compositions of matter are also disclosed. In addition, a guanine PNA synthon having selective carbamate protection of the exocyclic 2-amino group with the C6 carbonyl group unprotected is disclosed.
