Specifications Mini Spin Columns with collection tube use for DNA/RNA extraction., Silica Membrane Mini RNA pextraction column Spin Column are based on proprietary silica membrane purification technology. In addition to the spin column itself, each spin column comes with one outer collection tube ,one frit, one silica membrane and one fixing ring. Under low pH and chaotropic conditions, nucleic acids specifically bind to silica membrane while polysaccharides and proteins pass through. Impurities are further removed by washing. Finally, under low-salt conditions, nucleic acids are desorbed and eluted from the membran. TZ DNA Silica Membrane Mini Spin Columns Compatible with Qiagen, life, promega, Invitrogen and other top brands buffers. It has been widely used as a low cost substitute for Qiaprep*, Qiaquick*, Qiaamp*, DNeasy*, RNeasy*, PureLink*, GeneElute*, PureYield*, and more. In a stand alone single column format, its application covers from DNA to RNA, from plasmid to viral and genomic DNA, from regular PCR purification to next generation sequencing sample preparation.By now, millions of pieces have served scientists around the world. TZ all in one Spin Column is also compatible with a wide range of the other brand buffers* Choose TZ spin columns the Buffer recipes** can be supplied for free.
