We developed a general restriction enzyme-free and ligase-free method for subcloning up to three DNA fragments into any location of a plasmid. The DNA multimer generated by prolonged overlap extension PCR was directly transformed in Escherichia coli [e.g., TOP10, DH5α, JM109, and BL21(DE3)] and Bacillus subtilis for obtaining chimeric plasmids.
我们开发了一种通用的无需限制酶和连接酶的方法,可将多达三个 DNA 片段亚克隆到质粒的任何位置。通过长片段重叠延伸 PCR 产生的 DNA 多聚体可直接转化到大肠杆菌[如 TOP10、DH5α、JM109 和 BL21(DE3)]和枯草芽孢杆菌中,以获得嵌合质粒。
