DNA的凝膠電泳(gel-electrophoresis)
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
