    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)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

    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
