We describe here an improved megaprimer PCR mutagenesis strategy. The cumbersome gel purification step that is usually used can be omitted by appropriately cleaving the first and second DNA templates with restriction enzymes and enzymatically removing remaining primers from the first PCR reaction. We show that this improved procedure is reproducible and highly efficient. Furthermore this method is suitable for automation because all the steps are now carried out in reaction tubes.
我们在此描述一种改进的大引物PCR诱变策略。通过用限制酶适当切割第一和第二DNA模板,并从第一次PCR反应中酶促去除剩余引物,通常使用的繁琐凝胶纯化步骤可以省略。我们表明,这种改进的方法具有可重复性且效率很高。此外,该方法适用于自动化,因为现在所有步骤都在反应管中进行。
