This kit uses an optimized buffer system and silica gel column purification technology, which can recover 70 bp-20 kb DNA fragments from various concentrations of TAE or TBE agarose gels, and transfer them to the DNA adsorption column under high salt conditions. Direct centrifugation can specifically adsorb DNA and remove other impurities. In addition, this kit can directly purify DNA fragments from PCR products, enzymatic reaction systems or crude DNA products obtained by various other methods, while removing impurities such as proteins, other organic compounds, inorganic salt ions, and oligonucleotide primers. . It can ensure that the purification work is completed in 10-15 min. The purified DNA can be directly used for molecular biology research such as ligation, transformation, restriction enzyme digestion, in vitro transcription, PCR, sequencing, and microinjection.   Simple and fast; One box for dual use; High recovery efficiency; Wide range of recovered DNA fragments   Store at room temperature (15-25℃)
