Abstract

A general, simple and efficient method for preparing site-specific mutations in double-stranded plasmid DNA without the need for special plasmids, bacterial strains or reagents is described. Only one synthetic oligonucleotide for each mutation is required, subcloning is unnecessary and a high efficiency of mutation (58-97%) was obtained. If two synthetic oligonucleotide primers are used, two separate mutations can be simultaneously created in a single reaction tube.

摘要

本文描述了一种通用、简单且高效的方法,用于在双链质粒DNA中制备位点特异性突变,无需特殊质粒、细菌菌株或试剂。每个突变仅需一个合成寡核苷酸,无需亚克隆,且获得了较高的突变效率(58-97%)。如果使用两个合成寡核苷酸引物,则可在单个反应管中同时产生两个独立的突变。
