Usages: For isolation and enumeration of coagulase-positive staphylococci in foodstuffs.
Principle: Tryptone, beef extract powder and yeast extract powder provides carbon and nitrogen sources, vitamins and growth factors; sodium pyruvate and glycine to stimulate the growth of Staphylococcus aureus; lithium chloride and potassium tellurite inhibit the non-staphylococcal microorganisms; containing lecithinase staphylococcal colonies produce degradation yolk make transparent circle, while the role of the lipase produced an opaque precipitate ring; coagulase-positive staphylococci can restore potassium tellurite and produce black colonies; agar is medium coagulant.

The MagPure Plasmid purification system uses the paramagnetic bead technology for high-throughput preparation of high-copy or low-copy plasmid DNA from E. coli cells. This kit also can be used with fosmid and BAC vector-based constructs. The system uses alkaline lysis followed by a MagPure purification to differentially bind plasmid DNA to paramagnetic beads. While the DNA is bound to the beads, contaminants can be rinsed away using a simple washing procedure. Because MagPure uses magnetic separation technology, the protocol does not require vacuum filtration. This makes kit extremely amenable to automation. Plasmid DNA purified with this system is most commonly used in Sanger Sequencing and PCR amplification.

Principle
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 Lysozyme. 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.
Advantages
High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
Fast – it takes only 80 minutes to complete the isolation
High yield – up to 15μg plasmid can be binded in one column
RNase A and MagPure Particles should be stored at 2–8°C upon arrival. However, short-termstorage (up to 12 weeks) at room temperature (15–25°C) does not affect its performance. Theremaining kit components can be stored dry at room temperature (15–25°C) and are stable for atleast 18 months under these conditions.The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature whenused. If any precipitates form in the buffers,warm at 37℃ to dissolve. After addition of RNase A, Buffer P1 is stable for 6 months when stored at

This product provides a fast and easy way to purify DNA from plant and fungal tissue. Up to 100 mg of tissue can be processed. Easy-to-use Plant procedures provide pure total DNA (genomic,mitochondrial, and chloroplast) for reliable PCR and southern blotting in less than 1 hour. Purification requires no phenol or chloroform extraction oralcohol precipitation and involves minimal handling.
Plantmaterial is first mechanically disrupted and then lysed by addition of lysis buffer and incubation. RNase A in the lysis buffer digests the RNA in the sample. After lysis, proteins and polysaccharides are salt-precipitated.Binding buffer and ethanol are added to the cleared lysate to promote binding of the DNA to the HiPure membrane. The sample is then applied to a column and then centrifuged. DNA binds to the membrane, while contaminants such as proteins and polysaccharides are efficiently removed by 2 wash steps. Pure DNA is eluted in a small volume of low-salt buffer or water.
Advantages
Safe – require no phenol or chloroform extraction
Fast – several samples can be extracted in 30 minutes by silica technology
High purity – high quality DNA, completely remove inhibitors
High yield – silica technology can achieve the highest yield
