功能基因组学需要构建用于蛋白质表达和靶基因功能表征的载体;因此,简单、灵活和低成本的分子操作策略对于基因组学方法将是非常有利的。在这里,我们描述了一种Ω-PCR策略,该策略能够在环状质粒的任何位置进行多种类型的序列修饰,包括精确插入、缺失和取代。Ω-PCR基于重叠延伸定点突变技术,并因其在PCR过程中的特征性Ω形二级结构而命名。Ω-PCR可以分两步进行,也可以在一个试管中与核酸外切酶I处理组合进行。这些策略在蛋白质工程、基因功能分析和体外基因拼接等方面有着广泛的应用。
Functional genomics requires vector construction for protein expression and functional characterization of target genes; therefore, a simple, flexible and low-cost molecular manipulation strategy will be highly advantageous for genomics approaches. Here, we describe a Ω-PCR strategy that enables multiple types of sequence modification, including precise insertion, deletion and substitution, in any position of a circular plasmid. Ω-PCR is based on an overlap extension site-directed mutagenesis technique, and is named for its characteristic Ω-shaped secondary structure during PCR. Ω-PCR can be performed either in two steps, or in one tube in combination with exonuclease I treatment. These strategies have wide applications for protein engineering, gene function analysis and in vitro gene splicing.
