摘要: 将受体菌与质粒DNA混匀直接在Ca2+离子选择平板上进行转化和筛选,其转化过程仅需2 min左右,并能得到105以上的转化效率, 可满足一般克隆工作的需要。
Abstract:After mixing the recipient cells and plasmids DNA, directly spread the mixture on selective media containing Ca2+. The whole process of transformation just needs 2 min or so, and could acquire the transformation efficiency of more than 105, which is enough to common gene cloning.
