    • The invention provides a method of nucleic acid sequence analysis based on repeated cycles of ligation to and cleavage of probes at the terminus of a target polynucleotide. At each such cycle one or more terminal nucleotides are identified and one or more nucleotides are removed from the end of the target polynucleotide, such that further cycles of ligation and cleavage can take place. At each cycle the target sequence is shortened by one or more nucleotides until the nucleotide sequence of the target polynucleotide is determined. The method obviates electrophoretic separation of similarly sized DNA fragments and eliminates the difficulties associated with the detection and analysis of spacially overlapping bands of DNA fragments in a gel, or like medium. The invention further obviates the need to generate DNA fragments from long single stranded templates with a DNA polymerase.
    • 本发明提供了基于在靶多核苷酸的末端连接和切割探针的重复循环的核酸序列分析方法。 在每个这样的循环中,鉴定一个或多个末端核苷酸并从靶多核苷酸的末端去除一个或多个核苷酸,从而可以进一步进行连接和切割循环。 在每个循环中,靶序列缩短一个或多个核苷酸,直到确定靶多核苷酸的核苷酸序列。 该方法避免了类似大小的DNA片段的电泳分离,并消除了与凝胶或类似培养基中DNA片段的空间重叠带的检测和分析相关的困难。 本发明进一步避免了用DNA聚合酶从长单链模板产生DNA片段的需要。

    • The invention provides a system and reagents for carrying out multiplexed analytical measurements using the hybridization of oligonucleotide tags to addressable solid phase supports to obtain simultaneous readouts from hundreds to tens of thousands of reactions. In one aspect of the invention, analyte interaction moieties, such as oligonucleotide probes, are produced that are each labeled with a unique synthesis tag constructed from a set of two-nucleotide “words.” During or after an assay, the synthesis tags are converted to hybridization tags that are used in the readout step. Hybridization tags are constructed to maximize discrimination in the readout. Hybridization tags of the invention are preferably constructed from oligonucleotide “words” selected from a minimally cross-hybridizing set using combinatorial synthesis techniques. In a further aspect, discrimination in the readout is enhanced by employing hybridization tags that are constructed with words having the “comma-less” property and by minimizing or eliminating extraneous nucleic acids associated with the hybridization tag during a readout step.
    • 本发明提供了一种系统和试剂,用于使用寡核苷酸标签与可寻址固相载体的杂交来进行多重分析测量,以获得从数百到数万个反应的同时读数。 在本发明的一个方面,产生分析物相互作用部分,例如寡核苷酸探针,每个标记有由一组两核苷酸“单词”构成的唯一合成标签。 在测定期间或之后,将合成标签转化为在读出步骤中使用的杂交标签。 构建杂交标签以最大化读出中的区分。 本发明的杂交标签优选由使用组合合成技术的从最小交叉杂交组中选出的寡核苷酸“词”构建。 在另一方面,通过使用由具有“无逗号”性质的词组构成的杂交标签,以及通过在读出步骤期间最小化或消除与杂交标签相关的外来核酸来增强阅读中的鉴别。
