Application

Chelex is used in affinity chromatography, protein chromatography, chelating resins, affinity resins and core bioreagents.
Chelex® 100 sodium form has been used:
  • for the extraction of DNA from bee samples
  • to remove from cigarette smoke extract (CSE) and study the effects of hepcidin expression in the murine lungs
  • to extract DNA from bacterial cultures

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.
