琼脂糖凝胶电泳（agarose－gel－electrophoresis）介绍
主要试剂：核酸电泳缓冲液有三种，即Tris-硼酸(TBE)、Tris-乙酸(TAE)和Tris-磷酸(TPE).TBE与TPE缓冲容量高，DNA分离效果好，但TPE在DNA段回收时含磷酸盐浓度高，容易使DNA沉淀.TAE缓冲容量低，但价格较便宜，因而推荐选用TBE.缓冲液中的EDTA可螯合二价阳离子
琼脂糖凝胶电泳（agarose－gel－electrophoresis）检测DNA
原理： 琼脂糖是从海藻中提取出来的一种线状高聚物，可作为电泳支持物，适用于分离大小范围在0.2-50kb的DNA片段。DNA分子的迁移率与分子量的对数值成反比关系。观察其迁移距离，与标准DNA片段进行对照，就可获知该样品分子量大小。在质粒抽提过程中，由于各种因素的影响，使质粒DNA呈现超螺旋的共
