1) Dissolve 1 g of agarose in 100 ml of 1X TAE or TBE buffer (gives a 1% gel). See note for making LMP agarose gel. 2) Cast the gel with the comb in place.3) Add 6X gel loading buffer to sample and load the samples into wells.4) Run the gel submerged in 1X TAE or TBE (30-60 min. at 100-150V)5) Stain the gel with ethidium bromide solution (10 µl per 100ml of buffer) for 10 - 15 min. 6) View on a long wave UV......阅读全文
DNA酶切及凝胶电泳（gel－electrophoresis）1
第一节 概 述 一. DNA的限制性内切酶酶切分析 限制性内切酶能特异地结合于一段被称为限制性酶识别序列的DNA序列之内或其附近的特异位点上，并切割双链DNA。它可分为三类:Ⅰ类和Ⅲ类酶在同一蛋白质分子中兼有切割和修饰(甲基化)作用且依赖于ATP的存在。Ⅰ类酶结合于识别位点并随机的切割识别位
