RestrictionEnzymeBuffer
Restriction Enzyme Buffer Most enzymes can use REact buffers; however, some are made up separately. Use fresh Milli-Q water, siliconized or sterile glassware or disposable plastic ware to make the following stock solutions up fresh (discard after use), combine to make 5 ml of 10X reaction buffers, put 1 ml in to each of 5 microfuge tubes (MFTs) and store the current one at -20C and the rest at -70C.A: 1 M T......阅读全文

限制性内切酶（restriction－enzyme）酶谱分析
一、实验目的在DNA上以限制性内切酶的酶切位点作为标记所绘制的物理图谱就是限制性内切酶图谱，限制性内切酶图谱与其他相关资料联合使用，可用于基因克隆、分离和基因功能研究。二、实验原理（一）酶切图谱的构建限制性内切酶在DNA上有特异的识别和切割位点，可将DNA切开而得到两个或两个以上的大小不同的片段，这
DNA分子的限制性内切酶（Restriction－enzyme－,－endonuclease）消...
限制性内切酶可特异地结合于一段被称为限制酶识别序列的DNA 序列位点上并在此切割双链DNA 。绝大多数限制性内切酶识别长度为4、5或6个核苷酸且呈二重对称的特异序列，切割位点相对于二重对称轴的位置因酶而异。一些酶恰在对称轴处同时切割 DNA 双链而产生带平端的DNA 片段，另一些酶则在对称轴

常见限制性内切酶识别序列(酶切位点)
常见限制性内切酶识别序列(酶切位点)（BamHI、EcoRI、HindIII、NdeI、XhoI等）在分子克隆实验中，限制性内切酶是必不可少的工具酶。无论是构建克隆载体还是表达载体，要根据载体选择合适的内切酶（当然，使用T载就不必考虑了）。先将引物设计好，然后添加酶切识别序列到引物5' 端。
