    • The present invention relates to a method for the comparative assessment of the level of specific nucleic acid sequences in samples derived from different sources. More specifically, the invention relates to a method using oligonucleotides covalently linked to a solid support, such as beads, to isolate specific labeled nucleic acid sequences from complex mixtures. The methods disclosed allow quantitative comparisons of the amount of nucleic acid of defined sequence in a plurality of different samples of nucleic acid, e.g., from different cells or tissues or from genetic libraries. Nucleic acids from the samples are labeled in such a fashion that the signals can be distinguished and compared following hybridization to the oligonucleotides on the beads. According to the invention, the solid supports with the hybridized nucleic acid may be retrieved, and the target nucleic acid eluted and analyzed. Furthermore, the invention provides a method for tagging individual clones from a cDNA library such that they can be identified uniquely and retrieved by hybridization to specific beads.
    • 本发明涉及用于比较来自不同来源的样品中特异性核酸序列水平的比较评估方法。 更具体地,本发明涉及使用与固体支持物(例如珠)共价连接的寡核苷酸以从复杂混合物中分离特异性标记的核酸序列的方法。 所公开的方法允许定义的序列的核酸量在多个不同的核酸样品中,例如来自不同的细胞或组织或来自遗传图谱库的定量比较。 来自样品的核酸以这样的方式进行标记,即在与珠上的寡核苷酸杂交后可以区分和比较信号。 根据本发明,可以检索具有杂交核酸的固体支持物,并洗脱和分析靶核酸。 此外,本发明提供了一种用于从cDNA文库标记单个克隆的方法,使得它们可以被独特地鉴定并通过与特定珠子的杂交获得。
