We describe a novel PCR-based method that allows the generation of nested termination fragments by integrating both selective DNA amplification and directed chain termination into a single PCR reaction. These termination fragments can be examined for sequence variation in either denaturing or non-denaturing polyacrylamide gels. This method provides a one-step and highly effective approach for the detection of both insertions/deletions and single base pair substitutions in sequences up to 1 kb in length.
我们描述了一种基于聚合酶链式反应(PCR)的新方法,该方法通过将选择性DNA扩增和定向链终止整合到单个PCR反应中,从而生成嵌套终止片段。这些终止片段可以在变性或非变性聚丙烯酰胺凝胶中检测序列变异。该方法为检测长度达1 kb的序列中的插入/缺失和单碱基对替换提供了一种一步到位且高效的方法。
