    摘要: In one aspect, the present invention concerns methods and kits for quantifying a target nucleic acid in a sample. In embodiments, a method comprises sequestrating the target nucleic acid by one or more interactors to form a sequestered conjugate that will be further labeled to form a labeled conjugate. The signal produced by the labeled conjugate is measured and correlated to the amount of the target nucleic acid. In another aspect, the present invention concerns a method for quantifying a target nucleic acid in a sample by a reaction of the nucleic acids in the sample with a nucleic acid interactor or set of interactors to form a conjugate. The conjugate is then sequestered from the rest of the sample with a molecule bound to a support, to form a sequestered conjugate. The sequestered conjugate is labeled to form a labeled conjugate. The signal produced by the labeled conjugate is measured and correlated to the amount of the target nucleic acid. In some embodiments, the target nucleic acid is cell free nucleic acids. In embodiments, the interactor binds to nucleic acids in the sample in a nonsequence specific manner.

    摘要: The present invention relates to a method for labelling a product, to a method for identifying the labelling and to a product labelled by means of the method of the invention. The labelling used in the present invention is based on single-stranded nucleic acids. The labelling method of the present invention comprises a step of addition of a plurality of single-stranded polynucleotides onto or into said product, said plurality of polynucleotides comprising: at least one target polynucleotide comprising a single-stranded polynucleotide of predetermined length and sequence, and decoy polynucleotides which have identical or different predetermined lengths and identical or different predetermined sequences, said decoy polynucleotides having a length or lengths identical to or different from and sequences different from the sequence of said, at least one, target polynucleotide, in which each of the target polynucleotide(s) and decoy polynucleotides does not hybridize with any of the other polynucleotides of said plurality of polynucleotides. The method of the invention makes it possible, for example, to label fragrances, cosmetics, hygiene products, food products, flavourings, extracts of a plant or plants, tobacco, beverages, textiles, leathers, medicaments, powders, varnishes, inks, hydrocarbons, papers, paints, and chemical products and compounds.
