Introduction
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

ArcticZymes’ Shrimp Alkaline Phosphatase (SAP), including its recombinant version (rSAP), is the gold standard and the first heat-labile, all-purpose alkaline phosphatase on the market.
Originally isolated from Pandalus borealis (Arctic shrimp), it has been purified from a recombinant source since 2010. Unlike other alkaline phosphatases, rSAP can be fully inactivated by a short heat treatment of 15 minutes at 65°C.
This added convenience through complete heat inactivation has made SAP one of the most sold DNA modifying enzymes.
For added flexibility, especially when lyophilisation may be desired, rSAP is also available in a Glycerol FREE format. First launched in 1993, SAP’s unique features continue to make it a valuable tool in various applications.
Key Features
Gold standard heat labile, all-purpose alkaline phosphatase.
Completely inactivated after 5 min at 65°C or 1 min at 75°C.
Robust: Active in most restriction enzyme buffers, no need for supplemental zinc or other additives for activity.
Simple, hassle-free dephosphorylation of DNA, RNA, dNTPs and proteins for subsequent use in cloning or end-labelling of probes.
No vector purification necessary.
Easy inactivation of unincorporated dNTPs in PCR products prior to DNA sequencing or SNP analysis.
Ideal for MALDI-TOF, cloning, HLA typing, genotyping and sequencing.
Preparing substrate in protein kinase studies.
