Features

  • Archive-quality DNA for long-term storage
  • Reproducible DNA purification
  • Convenient, scalable purification procedure

Product Details

Puregene Accessories used in combination with 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 large-volume samples to be purified for use as long-term references.

To improve availability 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.

Principle

Using Puregene Kits, 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

Archive-quality DNA 

Purity of DNA has a significant effect on the accuracy of results obtained in downstream applications. Sensitive downstream applications, such as PCR, demand the use of DNA of the highest quality and molecular weight for reliable results. Puregene Kits removes 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. 

Applications

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

  • DNA archiving
  • PCR
  • SNP analysis
  • Southern blotting
  • NGS
  • Long-read sequencing

FAQ

What is the composition of RBC Lysis Solution?
The exact composition of RBC Lysis Solution is confidential. RBC Lysis Solution is a component of Gentra Puregene Blood Kits. RBC Lysis Solution selectively lyses human red blood cells leaving white blood cells intact. You can order RBC Lysis Solutin separately.
FAQ ID -2808
What is the composition of DNA Hydration Solution in Gentra Puregene Kits?

The composition of DNA Hydration Solution is as follows:

  • 10 mM Tris
  • 1 mM EDTA
  • pH 7–8

DNA Hydration Solution is included in QIAGEN’s Gentra Puregene Kits for DNA purification and can also be bought separately from QIAGEN.

FAQ ID -2813
What is the composition of Cell Suspension Solution?
The detailed composition of Cell Suspension Solution is confidential. Cell Suspension Solution is a component of the Gentra Puregene Yeast/Bacteria Kit. Essentially, it is an isotonic solution that prevents spheroblasts from bursting. Cell Suspension Solution can be ordered separately.
FAQ ID -2811
What is the composition of Protein Precipitation Solution?
The exact composition of Protein Precipitation Solution is confidential. Protein Precipitation Solution is a component of Gentra Puregene Kits for DNA purification. Essentially, this is a high-salt buffer that lowers the solubility of proteins. Protein Precipitation Solution can be ordered separately.
FAQ ID -2810
What is the composition and concentration of Glycogen Solution in Gentra Puregene Kits?
The exact composition of Glycogen Solution is confidential. The Glycogen concentration is 20mg/mL. Glycogen Solution is a component of Gentra Puregene Kits for DNA purification. During isopropanol precipitation, Glycogen Solution acts as a nucleic acid carrier and helps to efficiently precipitate small amounts of DNA. In addition, it facilitates visualization of the DNA pellet. Glycogen Solution can be purchased separately.

 

Note: Glycogen Solution does not work in combination with QIAGEN’s silica membrane technologies, e.g., RNeasy, DNeasy, QIAamp, etc. With these technologies, poly-A carrier RNA is used when dealing with low amounts of nucleic acids.
