    • The invention encompasses methods for enriching for and identifying a polymorphism within a nucleic acid sample either by separating a subset of a nucleic acid sample or by selectively replicating a subset of a nucleic acid sample such that the polymorphism is contained within a nucleic acid population with reduced complexity, and then identifying the polymorphism within the enriched nucleic acid sample. Methods also are disclosed for enriching for and identifying a polymorphism by contacting a nucleic acid sample that includes a subset of nucleic acid molecules having a sequence that binds to a sequence-specific binding activity with a molecule having a sequence-specific binding activity under conditions which permit specific binding, such that the subset of nucleic acid molecules bound to the activity is enriched for nucleic acid molecules having the sequence recognized by the sequence-specific binding activity, and detecting a polymorphism with respect to a reference sequence in the subset of nucleic acid molecules.
    • 本发明包括用于通过分离核酸样品的子集或通过选择性复制核酸样品的子集来使得核酸样品中的多态性富集和鉴定核酸样品中的多态性的方法,使得多态性包含在具有降低的核酸群体的核酸群体内 复杂性,然后鉴定富集的核酸样品内的多态性。 公开了通过使包含具有与序列特异性结合活性结合的序列的核酸分子的子集与具有序列特异性结合活性的分子的核酸样品接触的方法来丰富和鉴定多态性的方法, 允许特异性结合,使得与活性结合的核酸分子的子集富含具有由序列特异性结合活性识别的序列的核酸分子,并且检测核酸子集中的参考序列的多态性 分子。
