一、原理瓊脂糖或聚丙烯酰胺凝膠是分離和純化DNA片段的標準方法。聚丙烯酰胺凝膠電泳適用于分離小分子的核酸；瓊脂糖凝膠孔徑較大，被應用于大分子核酸的分離和純化。在一定濃度的瓊脂糖凝膠介質中，DNA分子的電泳遷移率與其分子量的常用對數成反比。當用低濃度的熒光嵌入染料溴化乙啶（EB）染色，在紫外光下至少可

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
凝膠電泳（gel－electrophoresis）的注意事項
影響電泳分離的主要因素：待分離生物大分子的性質：待分離生物大分子所帶的電荷、分子大小和性質都會對電泳有明顯影響。一般來說，子帶的電荷量越大、直徑越小、形狀越接近球形，則其電泳遷移速度越快。2. 緩沖液的性質：緩沖液的pH值會影響待分離生物大分子的解離程度，從而對其帶電性質產生影響，溶液pH值距離

凝膠電泳(gel－electrophoresis)操作注意事項
1.緩沖系統：在沒有離子存在時，電導率最小，DNA不遷移，或遷移極慢，在高離子強度的緩沖液中，電導很高并產熱，可能導致DNA變性，因此應注意緩沖液的使用是否正確。長時間高壓電泳時，常更新緩沖液或在兩槽間進行緩沖液的循環是可取的。2.瓊脂糖：不同廠家、不同批號的瓊脂糖，其雜質含量不同，影響DNA的遷移
