Biochem/physiol Actions
Chelex® 100 is a styrene-divinylbenzene copolymer containing paired iminodiacetate ions, which act as chelating groups in binding polyvalent metal ions. It is considered a weakly acidic resin. Chelex acts as a chelating resin that is used in DNA extraction from forensic samples, such as hair, bloodstain cards, and buccal swabs.
