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

DNA琼脂糖凝胶电泳（agarose－gel－electrophoresis）分析
一、原理琼脂糖凝胶具有分子筛效应。在中性ppH值的电泳缓冲液体系中，DNA分子由于带负电荷，所以在电场作用下由负极向正极泳动。由于DNA分子的大小和构型不同，在相同的时间内迁移至不同的位置。凝胶经溴化乙锭染色后，紫外检测仪下观察，即可看见DNA片段按大小不同呈条带分布。由于在一定条件下，DNA的迁移
