瓊脂糖凝膠電泳（agarose－gel－electrophoresis）介紹
主要試劑：核酸電泳緩沖液有三種，即Tris-硼酸(TBE)、Tris-乙酸(TAE)和Tris-磷酸(TPE).TBE與TPE緩沖容量高，DNA分離效果好，但TPE在DNA段回收時含磷酸鹽濃度高，容易使DNA沉淀.TAE緩沖容量低，但價格較便宜，因而推薦選用TBE.緩沖液中的EDTA可螯合二價陽離子
DNA瓊脂糖凝膠電泳（agarose－gel－electrophoresis）分析
一、原理瓊脂糖凝膠具有分子篩效應。在中性ppH值的電泳緩沖液體系中，DNA分子由于帶負電荷，所以在電場作用下由負極向正極泳動。由于DNA分子的大小和構型不同，在相同的時間內遷移至不同的位置。凝膠經溴化乙錠染色后，紫外檢測儀下觀察，即可看見DNA片段按大小不同呈條帶分布。由于在一定條件下，DNA的遷移
