Chelex 100 Chelating Resin, analytical grade, 100–200 mesh, sodium form, 500 g 1422832

500 g, cation exchange resin, sodium form, 1% crosslinkage, 100–200 dry mesh size, 150–300 µm wet bead size, ~3,500 MW limit

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
