QIAEX II Gel Extraction Kit

For purification of DNA fragments (40 bp to 50 kb) from gels and solutions
  • Efficient extraction of DNA from 40 bp to 50 kb
  • Gel extraction from TAE or TBE agarose gels and polyacrylamide gels
  • No sodium iodide to interfere with subsequent reactions
  • No shearing of large DNA fragments
The QIAEX II Gel Extraction Kit provides a suspension of silica particles to which DNA fragments bind in the presence of chaotropic salts. QIAEX II Suspension is added to solutions or solubilized agarose gel slices and binds DNA. The particles are collected by a brief centrifugation, washed, and DNA from 40 bp to 50 kb is eluted in Tris buffer or water.
