Chelex 100 and COVID-19
Streamline your viral RNA extraction with Chelex 100 Resin
or Instagene Matrix.
Chelex 100 Resin is made of a styrene divinylbenzene copolymer containing paired iminodiacetate ions, which act as chelating groups in binding polyvalent metal ions. The carboxylic acid groups of Chelex 100 Resin classify it as a weak cation exchange resin, but it differs from other exchangers in this class by featuring uniquely high selectivities for metal ions and much higher bond strengths.
Chelex 100 has a stronger selectivity for copper, iron, and other heavy metal ions over monovalent cations such as sodium and potassium. Its selectivity for divalent over monovalent ions is approximately 5,000 to 1, and it has a strong affinity for transition metals, even in highly concentrated salt solutions.
The following forms of Chelex 100 Resin are available:
- Analytical grade Chelex 100 Resin — exhaustively sized, purified, and converted; suitable for accurate, reproducible analytical techniques
- Biotechnology grade Chelex 100 Resin — the analytical grade is certified to contain fewer than 100 microorganisms per gram of resin
- Molecular biology grade Chelex 100 Resin — certified to be endo- and exonuclease-free and contain no ligase inhibitors
