The QIAquick and MinElute systems use a simple bind-wash-elute procedure with spin columns or a vacuum manifold.
|Analysis of PCR products before (b) and after (a) purification with the QIAquick PCR Purification Kit is shown. Samples were analyzed on a 1% TAE agarose gel. M: markers.|GelPilot Loading Dye contains three tracking dyes to facilitate optimization of DNA resolution.

|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
QIAquick PCR Purification操作流程去除引物、核苷酸、酶、矿物油、盐和DNA样本中的其他杂质(参见"Complete primer removal after PCR")。通过使用微型离心机或者真空底座,可以纯化得到100 bp–10 kb的DNA片段。
Principle

QIAquick Kits配备有硅胶膜,在高盐度缓冲液中结合DNA,应用低盐度缓冲液或水洗脱DNA。纯化过程去除引物、核苷酸、酶、矿物油、琼脂糖、溴化乙锭和DNA样本中的其他杂质(参见"Complete primer removal after PCR")。硅胶膜技术避免了松散树脂常见的问题和不便。特制的结合缓冲液可促进吸附特定片段范围内的DNA分子。 

凝胶上样染料

为更快、更方便地处理和分析样本,已提供凝胶上样染料。GelPilot Loading Dye含有3种示踪染料(二甲苯蓝、溴酚蓝和orange G),便于优化跑胶时间,避免小片段DNA跑得过远(参见"GelPilot Loading Dye")。

Procedure

QIAquick体系采用了简单的结合、洗涤、洗脱的流程(参见"QIAquick and MinElute procedure")。结合缓冲溶液可直接加入到PCR样本或者其他酶试剂中,然后将混合液上样到QIAquick离心柱。结合缓冲液含有pH值指示剂,可方便地确定DNA结合的最佳pH值(参见"pH Indicator Dye")。核酸在高盐度条件下结合到硅胶膜上,洗去杂质,使用小体积的低盐缓冲液或水洗脱纯DNA,得到的DNA可直接用于后续应用。 

处理过程

QIAquick 离心柱提供两个方便的操作方法。离心柱可放在传统的台式微型离心机上或通过适配器连接到任何真空底座上,如QIAvac 24 Plus和QIAvac Luer Adapters。QIAquick PCR Purification Kit以及其他的QIAGEN离心柱试剂盒可在QIAcube全自动核酸纯化仪器上全自动化运行,确保高产量和标准化的结果(参见"Spin column handling options A, B, C, D, and E")。

Applications

QIAquick系统纯化的DNA片段可直接用于各种应用,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。
