Here we describe a modified version of the digestion-ligation approach for efficient molecular cloning. In comparison with the original method, the modified method has the additional steps of gel purification and a second ligation after the first ligation of the linearized vector and DNA insert. During this process, the efficiency and reproducibility could be significantly improved for both stick-end cloning and blunt-end cloning. As an improvement of the very important molecular cloning technique, this method may find a wide range of applications in bioscience and biotechnology.
在此,我们描述了一种用于高效分子克隆的消化-连接方法的改进版本。与原始方法相比,改进后的方法在将线性化载体和DNA插入片段进行首次连接后,增加了凝胶纯化和第二次连接的步骤。在此过程中,粘端克隆和平端克隆的效率和可重复性都能得到显著提高。作为对这一非常重要的分子克隆技术的改进,该方法可能在生物科学和生物技术领域有广泛的应用。
