    • A method of characterizing an analyte sample is provided that includes the steps of: (a) anchoring the analyte to a nucleic acid template of known sequence; (b) conducting a DNA polymerase reaction that includes the reaction of a template, a non-hydrolyzable primer, at least one terminal phosphate-labeled nucleotide, DNA polymerase, and an enzyme having 3' 5' exonuclease activity which reaction results in the production of labeled polyphosphate; (c) permitting the labeled polyphosphate to react with a phosphatase to produce a detectable species characteristic of the sample; (d) detecting the detectable species. The method may include the step of characterizing the nucleic acid sample based on the detection. Also provided are methods of analyzing multiple analytes in a sample, and kits for characterizing analyte samples.

    • A method for determining the sequence of a target nucleic acid, including steps of contacting a target nucleic acid with a polymerase to sequentially remove nucleotide triphosphates from the target nucleic acid, wherein the nucleotide triphosphates that are removed have a variety of different base moieties; and distinguishing the different base moieties for the nucleotide triphosphates that are removed. Also provided is a apparatus including a nanopore positioned in a fluid impermeable barrier to form a passage through which a nucleotide triphosphate can pass from a first fluid reservoir to a second fluid reservoir, and a reaction mix in the first fluid reservoir that includes a polymerase, target nucleic acid having two strands, and pyrophosphoro lytic concentration of pyrophosphate.
    • 一种用于确定靶核酸序列的方法,包括使目标核酸与聚合酶接触以顺序地从靶核酸中除去三磷酸核苷酸的步骤,其中被去除的三磷酸核苷酸具有多种不同的碱基部分; 并区分待除去的三磷酸核苷酸的不同碱基部分。 还提供了一种装置,其包括定位在流体不可渗透屏障中的纳米孔,以形成三磷酸核苷从第一流体储存器传递到第二流体储存器的通道,以及包括聚合酶的第一流体储存器中的反应混合物, 具有两条链的靶核酸和焦磷酸焦磷酸溶解浓度。
