Product Details

Puregene Kits enable purification of high-molecular-weight (100–200 kb) DNA suitable for archiving. The scalable purification procedure gently removes contaminants and inhibitors and allows samples to be purified for use as long-term references.

To improve availability and address demand more efficiently we implemented an in-house manufacturing solution. This leads to product name and catalogue number changes . This Change will not reflect on the quality and performance of the products. The legacy products will be discontinued on 28.02.2022 and be available only until stocks last.

Please use the table in Performance to find the product you need.

Performance

The purity of DNA has a significant effect on the accuracy of results obtained in downstream applications. Sensitive downstream applications, such as PCR, demand use of DNA of the highest quality and molecular weight for reliable results. Puregene Kits remove contaminants and enzyme inhibitors, enabling purification of highly stable DNA well-suited for archiving. Purified DNA is of high quality demonstrated by molecular weights of 100–200 kb (see figures " Archive-quality DNA", “ High-molecular-weight DNA from tissue” and “ High-molecular-weight DNA from mouse tails”) and performs well in sensitive downstream applications including PCR and restriction digestion (see figure " Efficient restriction endonuclease digestion").

Archive-quality DNA.

High-molecular-weight DNA from tissue.

Reliable RNA isolation from a single cell.

Efficient restriction endonuclease digestion.

Principle

Cells are lysed with an anionic detergent in the presence of a DNA stabilizer. The DNA stabilizer limits the activity of intracellular DNases and also DNases found elsewhere in the environment. RNA is then removed by treatment with an RNA digesting enzyme. Other contaminants, such as proteins, are removed by salt precipitation. Finally, the genomic DNA is recovered by precipitation with alcohol and dissolved in hydration solution (1 mM EDTA, 10 mM Tris·Cl pH 7.5). Purified DNA typically has an A₂₆₀/A₂₈₀ ratio between 1.7 and 1.9 and is up to 200 kb in size. The DNA can be safely stored at 2–8°C, –20°C or –80°C.

Procedure

The simple Puregene procedure uses a modified salting-out precipitation method for purification of DNA (see flowchart " Puregene DNA procedure"). No mixing or dilution of solutions is necessary, and hands-on time is minimized. The procedure provides convenient stopping points that allow safe, temporary storage of partially purified samples.

EDTA chelates divalent cations which are required for nuclease activity. While the genomic DNA (gDNA) extracted using QIAGEN products, should not have any nuclease activity, it is possible to introduce nucleases during repeated long-term access of the DNA. EDTA helps to prevent any nuclease activity introduced after the genomic DNA extraction procedures.

However, if the gDNA is stored frozen at -20oC or -80oC, nuclease activity is much reduced. It may be possible to leave EDTA out of the storage buffer without negative consequences when samples are kept under these conditions, and when repeated freeze-thaw cycles are avoided.

We do recommend however that gDNA be stored in a neutral to a slightly basic buffered solution (e.g. 10 mM Tris-Cl pH 8.5 to 9.0) to prevent DNA degradation by acid hydrolysis. Note that deionized water mostly has an acidic pH.
