This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by Elution Buffer.

Storage and Stability
Proteinase K, RNase A, MagPure Particles should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
Experiment Data
This product is suitable for rapid extraction of DNA from tissue, cells, blood, saliva, swabs, blood spots, semen and other clinical samples. DNA can be used directly for PCR, quantitative PCR, Southern Blot, test of virus DNA and so on.
Intended Use
For the selective separation and enumeration of enterococci in food and water.
Principle and Interpretation
Tryptone and peptone are the sources of nitrogen and essential growth factors. Yeast extract acts as well nitrogenous compounds and additionally the vitamin B12 complex. Sodium azide acts largely inhibits the growth of gram-negative bacteria while sparing enterococci, staphylococci and streptococci. Ox bile inhibits most gram positives but not enterococci. Enterococci hydrolyse esculin to esculetin and dextrose, which reacts with ferric citrate producing a brownish black precipitate around the colonies. Tolerance to bile and the ability to hydrolyze esculin is the traditional and reliable test for the identification of enterococci. (4). Sodium chloride maintains the osmotic balance of the medium and Agar is the solidifying agent.
