    • The present invention provides methods for utilizing the changes of hybridization levels in time during approach to equilibrium duplex formation for identifying specific hybridization to polynucleotide probes. In the invention, the changes of hybridization levels at one or more polynucleotide probes by a sample comprising a plurality of nucleic acid molecules having different sequences are monitored during their progress towards equilibrium and the continuing increase of hybridization signals beyond cross-hybridization is used as an indication of specific binding. The invention also provides methods of comparing specificities of different polynucleotides probes. The invention further provides methods for ranking and selecting polynucleotide probes that are specific to particular nucleic acids and methods for enhancing the detection of nucleic acids. The invention further provides methods for determining the orientation of nucleotide sequences.
    • 本发明提供了在平衡双相形成过程中利用杂交水平随时间变化的方法,用于鉴定与多核苷酸探针的特异性杂交。 在本发明中,在包含具有不同序列的多个核酸分子的样品的一个或多个多核苷酸探针处的杂交水平的变化在其进展到平衡期间被监测,并且超越交叉杂交的杂交信号的持续增加用作 指示具体绑定。 本发明还提供了比较不同多核苷酸探针的特异性的方法。 本发明还提供了用于评估和选择对特定核酸特异性的多核苷酸探针的方法和用于增强核酸检测的方法。 本发明还提供了确定核苷酸序列取向的方法。
