Description
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
