氯化钠密度梯度离心法制备用于显微注射的外源DNA片段Sodium Chloride Step Gradients Centrifuge to Fractionate Foreign DNA Fragment for Microinjection
显微注射 氯化钠密度梯度离心 胚胎存活率 外源基因整合率
2007/12/31
摘要DNA显微注射是生产转基因动物最可靠和最常使用的一种方法，外源DNA的纯度对显微注射的成功起着至关重要的作用。本文介绍用氯化钠密度梯度离心的方法制备用于显微注射的外源DNA片段。与传统的琼脂糖凝胶回收的方法相比较，用此方法制备的外源DNA片段对小鼠受精卵进行显微注射后，受卵体母鼠的胚胎存活率,以及子代小鼠的外源基因整合率均有明显的提高。这一方法可为进一步提高转基因动物的成功率,提供方法学上的参...
