A simple and rapid procedure for screening transformant yeast colonies is described. In this method, a trace amount of plasmid DNA is isolated from a small amount of yeast cell mass; then, the presence of the exogenous DNA in each yeast colony is detected by PCR amplification.
本文描述了一种筛选转化酵母菌落的简单快速方法。在此方法中,从少量酵母细胞团中分离出微量质粒DNA;然后,通过PCR扩增检测每个酵母菌落中外源DNA的存在。
