QIAamp RNA Blood Mini Kit
For purification of cellular RNA from fresh whole blood
The QIAamp RNA Blood Mini Kit provides silica-membrane-based purification of cellular RNA from up to 1.5 ml of fresh, whole human blood stabilized with any common anticoagulant, such as citrate, heparin, or EDTA. After homogenization using the QIAshredder spin column, a fast spin-column procedure simplifies RNA purification. Purification can be fully automated on the QIAcube Connect.
The QIAamp RNA Blood Mini Kit is intended for molecular biology applications. This product is not intended for the diagnosis, prevention, or treatment of a disease.
The QIAamp procedure completely removes RNases, contaminants, and enzyme inhibitors, yielding high-quality RNA suitable for any downstream application (see figures "High-quality RNA for northern analysis" and "Reliable RT-PCR analysis").
The QIAamp RNA Blood Mini Kit provides the highest-quality RNA with minimum copurification of DNA. However, as with any RNA purification method, some DNA contamination can be expected. For certain RNA applications that are sensitive to very small amounts of DNA, it may be necessary to remove any remaining DNA. In these cases, the QIAGEN RNase-Free DNase Set provides convenient on-column DNase treatment of RNA samples during QIAamp RNA procedures.
The QIAamp RNA Blood Mini Kit provides purification of cellular RNA using silica-membrane technology. No phenol–chloroform extraction is required. RNA binds specifically to the QIAamp silica-gel membrane while contaminants pass through. PCR inhibitors, such as divalent cations and proteins, are completely removed in two efficient wash steps, leaving pure RNA to be eluted in either water or a buffer provided with the kit.
QIAamp technology yields total cellular RNA from fresh whole blood and other sample sources that is ready to use in RT-PCR and blotting procedures. QIAamp sample preparation technology is fully licensed.
The QIAamp RNA Blood Mini Kit simplifies isolation of RNA from blood with a fast spin-column procedure (see figure "Procedure"). Red blood cells are selectively lysed and white cells collected by centrifugation. White cells are then lysed using highly denaturing conditions which immediately inactivate RNases. After homogenization using the QIAshredder spin column, the sample is applied to the QIAamp spin column. Total RNA binds to the QIAamp membrane and contaminants are washed away, leaving pure RNA to be eluted in 30–100 µl RNase-free water (provided with the kit) for direct use in any downstream application.
The QIAamp RNA Blood Mini Kit is designed for isolation of cellular RNA from up to 1.5 ml of fresh, whole human blood stabilized with any common anticoagulant, such as citrate, heparin, or EDTA. In addition, total cellular RNA can be isolated from tissue samples.
