    • PROBLEM TO BE SOLVED: To provide a method and a system for solution-based sequence enrichment and analysis of genomic regions.SOLUTION: There is provided a method for isolating a plurality of nucleic acid sequences and reducing complexity of the plurality of nucleic acid sequences, comprising (a) a step of providing (i) a solid support including a hybridization probe hybridizable to a target nucleic acid sequence and (ii) a nucleic acid specimen containing the target nucleic acid sequence, (b) a step of amplifying the hybridization probe with primers, wherein one or both of the primers contain binding portions, the amplification product contains a binding portion, the amplification product is maintained in a solution, and the binding portion is bondable to the solid support, (c) a step of hybridizing the nucleic acid specimen to the amplification product in the solution in a manner to cause hybridization between the amplification product and the nucleic acid specimen, (d) a step of separating the target nucleic acid/amplification product hybridization complex from a non-specifically hybridized nucleic acid by the binding portion, and (e) a step of eluting the hybridized target nucleic acid sequence from the complex.
    • 要解决的问题:提供基于溶液的序列富集和基因组区域分析的方法和系统。解决方案:提供了分离多个核酸序列并降低多个核酸序列的复杂性的方法, 包括(a)提供(i)包含可与靶核酸序列杂交的杂交探针的固体支持物和(ii)含有靶核酸序列的核酸样品的固体支持物的步骤,(b)扩增杂交探针 使用其中一个或两个引物含有结合部分的引物,扩增产物含有结合部分,扩增产物保持在溶液中,结合部分可与固体支持物结合,(c)将 核酸标本以扩增产物和核酸标本之间的杂交的方式溶解于溶液中的扩增产物,(d)sep 通过结合部分来自非特异性杂交的核酸的靶核酸/扩增产物杂交复合物,和(e)从所述复合物中洗脱杂交的靶核酸序列的步骤。
