  Methods and compounds, including compositions therefrom, are provided for determining the sequence of nucleic acid molecules. The methods permit the determination of multiple nucleic acid sequences simultaneously. The compounds are used as tags to generate tagged nucleic acid fragments which are complementary to a selected target nucleic acid molecule. Each tag is correlative with a particular nucleotide and, in a preferred embodiment, is detectable by mass spectrometry. Following separation of the tagged fragments by sequential length, the tags are cleaved from the tagged fragments. In a preferred embodiment, the tags are detected by mass spectrometry and the sequence of the nucleic acid molecule is determined therefrom. The individual steps of the methods can be used in automated format, e.g., by the incorporation into systems.

  提供了用于确定核酸分子序列的方法和化合物，包括从中制备的组合物。该方法允许同时确定多个核酸序列。这些化合物被用作标记，以生成与所选目标核酸分子互补的带标记的核酸片段。每个标记与特定的核苷酸相关，在优选实施例中，可以通过质谱法检测到。在通过顺序长度分离带标记的片段后，将从带标记的片段中切除标记。在优选实施例中，通过质谱法检测标记，并从中确定核酸分子的序列。该方法的各个步骤可以以自动化格式使用，例如通过纳入系统中。

  Methods are provided for detecting the binding of a first member to a second member of a ligand pair, comprising the steps of (a) combining a set of first tagged members with a biological sample which may contain one or more second members, under conditions, and for a time sufficient to permit binding of a first member to a second member, wherein said tag is correlative with a particular first member and detectable by non-fluorescent spectrometry, or potentiometry; (b) separating bound first and second members from unbound members; (c) cleaving the tag from the tagged first member; and (d) detecting the tag by non-fluorescent spectrometry, or potentiometry, and therefrom detecting the binding of the first member to the second member.

  本发明提供了检测配体对中第一成员与第二成员结合的方法，包括以下步骤：(a) 在足以允许第一成员与第二成员结合的条件和时间下，将一组第一标记成员与可能含有一个或多个第二成员的生物样品结合，其中所述标记与特定的第一成员相关，并可通过非荧光光谱法或电位计法检测；(b) 将结合的第一和第二成员与未结合的成员分离； (c) 从标记的第一成员上裂解标记；以及 (d) 通过非荧光光谱法或电位测定法检测标记，并由此检测第一成员与第二成员的结合情况。
