    摘要: Provided is a sensitive method to specifically detect nucleic acid sequences using a combination of DNA replication based signal amplification (e.g., PCR) and lateral flow analyte detection. The disclosed method uses a dual-labeled DNA probe complementary to a region of the target DNA sequence. Cleavage of the probe, caused by the presence of the amplified DNA target, is detected using lateral flow methods.

    摘要: Assays and methods including mobile tagged single stranded nucleic acid reagents pre-loaded on an analysis device, which are preferably tagged, but not labeled and are complementary to a strand (preferably the anti-sense strand in double stranded DNA targets) of the target nucleic acid. The assay also includes a running buffer that includes a dye or other detectable label that nonspecifically binds only to double stranded nucleic acids. In addition, the analysis device includes a detection zone including one or more test zones that have an immobilized tag that binds to the tag on the mobile nucleic acid reagent.

    摘要: In some embodiments, a strand displacement system is provided. Such a system may include a first nucleic acid catalyst molecule; a nucleic acid gate molecule, wherein the first nucleic acid catalyst molecule binds the nucleic acid gate molecule forming a nucleic acid gate-catalyst complex and releases an output molecule; and a nucleic acid sink molecule. The nucleic acid sink molecule sequesters a putative second nucleic acid catalyst, wherein the second nucleic acid catalyst differs from the first nucleic acid catalyst molecule by at least one nucleotide. In some aspects, the first nucleic acid catalyst may include a biomarker of interest or a nucleic acid aptamer which binds an amino acid-based biomarker of interest.

    摘要: Provided are a method and a kit for accurately and rapidly detecting ten types of targeting pneumonia bacteria: Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, Chlamydophila pneumoniae, Legionella pneumophila, Klebsiella pneumoniae, Pseudomonas aeruginosa, Moraxella catarrhalis, methicillin-resistant Staphylococcus aureus (MRSA), and Staphylococcus aureus. A set of primer pairs directed to their respective target regions contained in the DnaJ gene, etc., of the ten types of pneumonia causative bacteria is designed for the ten bacterial strains and used to amplify gene products. A set of bacterial strain-specific probe pairs is further designed for the ten bacterial strains such that the probe pairs hybridize with the amplification products via sequences in the respective target regions differing from the sequences hybridized by the set of primer pairs. A first probe-bound labeled high molecular carrier in which plural types of first probes for the pneumonia bacteria are bound to a labeled high molecular carrier and a solid-phase second probe-carrying developing support are used as the set of probe pairs to perform nucleic acid chromatography.
