CHELEX 100 is a chelating material from Bio-Rad used to purify other compounds via ion exchange. It is noteworthy for its ability to bind transition metal ions.

It is a styrene-divinylbenzene co-polymer containing iminodiacetic acid groups.

A concentrated solution of metals is obtained by eluting the resin with a small volume of 2 M nitric acid, which protonates the iminodiacetate groups.

Chelex resin is often used for DNA extraction. Polar resin beads bind polar cellular components after breaking open cells. Non-polar nuclear DNA and RNA remain in water solution above chelex.
