DNA凝膠電泳（DNA－agarose－gel－electrophoresis）
實驗原理瓊脂糖凝膠電泳是常用的用于分離、鑒定DNA、RNA分子混合物的方法，這種電泳方法以瓊脂凝膠作為支持物，利用DNA分子在泳動時的電荷效應和分子篩效應，達到分離混合物的目的。DNA分子在高于其等電點的溶液中帶負電，在電場中向陽極移動。在一定的電場強度下，DNA分子的遷移速度取決于分子篩效應，即分

瓊脂糖凝膠電泳（agarose－gel－electrophoresis）檢測DNA
原理： 瓊脂糖是從海藻中提取出來的一種線狀高聚物，可作為電泳支持物，適用于分離大小范圍在0.2-50kb的DNA片段。DNA分子的遷移率與分子量的對數值成反比關系。觀察其遷移距離，與標準DNA片段進行對照，就可獲知該樣品分子量大小。在質粒抽提過程中，由于各種因素的影響，使質粒DNA呈現超螺旋的共
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
