Principles
- Lysis Process:
- Cells are lysed with an anionic detergent in the presence of a DNA stabilizer.
- The DNA stabilizer limits the activity of intracellular DNases and DNases in the environment.
- RNA Removal:
- RNA is eliminated by treatment with an RNA-digesting enzyme.
- Contaminant Removal:
- Other contaminants, like proteins, are removed by salt precipitation.
- DNA Recovery:
- Genomic DNA is recovered by precipitation with alcohol.
- The recovered DNA is dissolved in Buffer TE.
- Quality Assurance:
- Purified DNA typically exhibits an A260/A280 ratio between 1.7 et 1.9.
- DNA size can reach up to 200 ko.
Avantages
- Safe – without phenol-chloroform extraction
- Environment friendly – the reagents used are safe, non-toxic, and without pollution
- High molecular weight – the molecular weight of genomic DNA is about 50-150kb
- Haute pureté – the purified DNA has A260/280=1.8-1.9, A260/230=2.0-2.5
- Unlimited sample size – solution type operation, sample volume can be adjusted at will
- Cost performance – the most economical nucleic acid extraction technology
