低洗脱体积,从凝胶中纯化多达5 μg的DNA片段(70 bp到4 kb)

  • 非常小的洗脱体积
  • 纯化速度快,操作简单
  • 回收率高,重复性好
  • 含有凝胶上样染料,方便样本分析

MinElute Gel Extraction Kit含有离心柱、缓冲液和收集管,用于基于硅胶膜技术的DNA片段纯化,适用于从多达400 mg的凝胶胶条中纯化70 bp到4 kb的DNA。特殊设计的离心柱可将DNA洗脱至非常小的体积(10 μl),获得高产、高度浓缩的DNA。通过内置的pH指示剂可容易确定DNA结合到离心柱的最佳pH值。使用MinElute体系纯化的DNA片段可即用于各种应用,包括测序、微阵列分析、连接和转化、限制性酶切、标记、显微注射、PCR和体外转录。

|pH indicator dye in the solubilization and binding buffer allows easy visual determination of optimal pH for DNA adsorption (pH ≤7.5). An incorrect binding-mixture pH can occur if the agarose gel electrophoresis buffer was frequently used or incorrectly prepared. In this case, the pH can be easily adjusted by addition of 10 µl 3 M sodium acetate, pH 5.0.

Performance

MinElute Gel Extraction Kit纯化去除引物、核苷酸、酶、矿物油、盐、琼脂糖、溴化乙锭和DNA样品中的其他杂质,获得的高度浓缩的DNA可用于各种下游应用(参见"Higher DNA concentrations")。

MinElute QIAquick Gel Extraction Kit提供用于凝胶纯化的离心柱。使用微型离心机或真空装置快速纯化70 bp–4 kb的高度浓缩的DNA。(4 kb–10 kb的DNA片段使用QIAquick Gel Extraction Kit纯化,而小于70 bp或大于10 kb的片段使用QIAEX II Gel Extraction System纯化。)

Principle

MinElute Kits采用硅胶膜式纯化柱,在高盐条件下结合DNA,低盐或水可洗脱DNA。硅胶膜技术避免了松散树脂和悬液状态的问题及不方便性。经优化的特制结合缓冲液,专用于选择性吸附特定大小范围内的DNA分子。

凝胶上样染料

为更快速、更方便地进行分析,提供上样染料。GelPilot Loading Dye含有3种示踪染料(xylene cyanol、bromophenol blue和orange G),便于优化凝胶运行时间,避免小片段DNA跑得过远(参见"GelPilot Loading Dye")。

Procedure

MinElute体系应用简单的结合-洗涤-洗脱步骤(参见"MinElute procedure")。凝胶碎片溶解在含有pH指示剂的缓冲液中,可方便确定DNA结合的最佳pH值(参见pH Indicator Dye),然后将混合物装载到MinElute离心柱上。在高盐条件下,核酸吸附在硅胶膜上。洗去杂质并用少量的低盐缓冲液或水洗脱DNA,可即用于各种下游应用。

操作

MinElute离心柱提供两种操作(参见"MinElute procedure")。将离心柱放入传统的微型离心机或任何含有连接器的真空装置上,如带有QIAvac Luer Adapters的QIAvac 24 Plus。MinElute Gel Extraction Kit和QIAGEN的其他离心柱试剂盒,可在QIAcube全自动核酸纯化仪上全自动进行,可提高产量,获得标准化结果。

Applications

MinElute或QIAquick System纯化的DNA片段可直接用于多种下游应用,包括:

  • 测序,包括第二代测序
  • 微阵列分析
  • 连接和转化
  • 限制性酶切
  • 标记
