ELECTROPHORESIS OF DNA IN AGAROSE GELSA). AGAROSE CONCENTRATIONS: Use 0.8% agarose (w/v) for high molecular weight DNA fragments, and 1 - 1.2% for smaller DNA fragments. 0.5% gels are very flimsy and need to be handled with caution. Low melting agarose is used at the same concentration as regular agarose. We have used FMC's SeaPlaque agarose which melts at 65°C and solidif......阅读全文

DNA凝胶电泳（DNA－agarose－gel－electrophoresis）
实验原理琼脂糖凝胶电泳是常用的用于分离、鉴定DNA、RNA分子混合物的方法，这种电泳方法以琼脂凝胶作为支持物，利用DNA分子在泳动时的电荷效应和分子筛效应，达到分离混合物的目的。DNA分子在高于其等电点的溶液中带负电，在电场中向阳极移动。在一定的电场强度下，DNA分子的迁移速度取决于分子筛效应，即分

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
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

DNA片段的琼脂糖凝胶电泳（agarose－gel－electrophoresis）
【原 理】琼脂糖凝胶电泳是重组DNA研究中常用的技术，可用于分离，鉴定和纯化DNA片段。不同大小、不同形状和不同构象的DNA分子在相同的电泳条件下（如凝胶浓度、电流、电压、缓冲液等），有不同的迁移率，所以可通过电泳使其分离。凝胶中的DNA可与荧光染料溴化乙锭（EB）结合，在紫外灯下可看到荧光条带，籍
