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

凝胶电泳（gel－electrophoresis）的注意事项
影响电泳分离的主要因素：待分离生物大分子的性质：待分离生物大分子所带的电荷、分子大小和性质都会对电泳有明显影响。一般来说，子带的电荷量越大、直径越小、形状越接近球形，则其电泳迁移速度越快。2. 缓冲液的性质：缓冲液的pH值会影响待分离生物大分子的解离程度，从而对其带电性质产生影响，溶液pH值距离

凝胶电泳(gel－electrophoresis)操作注意事项
1.缓冲系统：在没有离子存在时，电导率最小，DNA不迁移，或迁移极慢，在高离子强度的缓冲液中，电导很高并产热，可能导致DNA变性，因此应注意缓冲液的使用是否正确。长时间高压电泳时，常更新缓冲液或在两槽间进行缓冲液的循环是可取的。2.琼脂糖：不同厂家、不同批号的琼脂糖，其杂质含量不同，影响DNA的迁移
