|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 PCR Purification过程去除引物、核苷酸、酶、矿物油、盐和DNA样品中的其他杂质(参见"Efficient primer removal")。

MinElute PCR Purification Kit提供离心柱,用于PCR产物的回收。使用微型离心机或真空装置快速获得高度浓缩的DNA片段(70 bp–4 kb)。(大于4 kb的DNA片段使用QIAquick PCR Purification Kit纯化。)
Principle

MinElute PCR Purification Kit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。

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 System应用简单的结合-洗涤-洗脱步骤。直接将结合缓冲液加入PCR样品或其他酶反应中,然后将混合液装载到MinElute离心柱上。结合缓冲液含有pH指示剂,可方便地确定DNA结合的最佳pH值(参见pH Indicator Dye)。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离心柱有两种方便的处理方式(参见"MinElute procedure")。可将离心柱放入传统的微型离心机或通过适配器连接到任何真空装置上,诸如通过QIAvac Luer Adapters连接到QIAvac 24 Plus或QIAvac 6S,也可在QIAcube全自动核酸纯化仪上全自动进行。

Applications

MinElute System纯化的DNA片段可直接用于各种下游应用,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
