Plasmid & DNA Fragments Kit

Preparations of DNA fragments (e.g. PCR fragments, gel bands, or plasmids) are required in many applications in molecular biology. The MSB product portfolio offers multiple benefits for this application based on the advantages of non-chaotropic chemistry. 


  • convenient and fast sample processing
  • the most efficient removal of contaminants
  • high recovery rate of PCR products or DNA fragments
  • broad range of fragment sizes 80 bp - 30 kb can be purified

The purification procedure has been optimized to remove salts, enzymes, nucleotides, mineral oil, agarose, ethidium bromide and other impurities from DNA samples. Specialized binding buffers promote selective adsorption of DNA fragments and PCR products. The pure DNA is eluted in a small volume of buffer or water, ready to use for any subsequent application.
