Choose analytical grade Chelex 100 Resin, a weak cation exchange media, for chelation, DNA extraction for PCR, and other cation exchange protocols. Use this sodium-form resin for gravity or low-pressure chromatography.

  • Medium-mesh resin is effective for both preparative and analytical protocols
  • Selectivity for divalent over monovalent ions is approximately 5,000 to 1
  • Strong attraction for transition metals, even in highly concentrated salt solutions
  • Inactivates enzymes, including DNases, that require divalent cations for activity
  • Larger volumes and special packaging are available upon request

*Biotechnology grade resin is certified to contain less than 100 microorganisms per gram; molecular-biology-grade resin is certified to be endo- and exonuclease-free and contain no ligase inhibitors.
