Choose molecular biology grade Chelex 100 Resin, a weak cation exchange media, for chelation, DNA or RNA preparation for PCR or RT-PCR, or other cation exchange protocols. Use this sodium-form resin for gravity or low-pressure chromatography.

  • Fine-mesh resin is effective for high resolution analytical protocols
  • High degree of selectivity for divalent over monovalent ions (approximately 5,000 to 1)
  • Strong attraction for transition metals, even in highly concentrated salt solutions
  • Inactivates enzymes, including metallo-nucleases, that require divalent cations for activity
  • Enables fast, easy and cost-effective method for nucleic acid preparations from many sample types including forensic, tissues, viruses and bacteria
  • Certified to be free of endo- and exonucleases, and ligase inhibitors
  • Larger volumes and special packaging are available upon request
