Product Details

Gentra 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.

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  and performs well in sensitive downstream applications including PCR and restriction 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 . 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.



Applications

DNA purified using Gentra Puregene Kits is highly stable and suited for use in a wide range of applications, such as:


DNA archiving

PCR

SNP analysis

Southern blotting


Supporting data and figures

Archive-quality DNA.

DNA was purified from replicate whole blood samples using the Gentra Puregene Blood Kit. Purified DNA was analyzed by agarose gel electrophoresis after storage for 18 years at 4°C. M1: Uncut Lambda DNA; M2: Lambda HindIII marker.
