Chelex 100 sodium form

Chelating resin: 50-100 mesh (dry), mainly used to remove divalent cations from solutions such as enzymes, but also to reduce the concentration of calcium and magnesium ions in the auxotroph. Chelating resins are polymer compounds that can selectively chelate specific metal ions in the form of ionic bonds or coordination bonds. Chelating resin is generally prepared by the chemical reaction of high polymer, with cross-linked polymer such as styrene/divinylbenzene resin as the skeleton, and the connection is composed of special functional groups. Monomers containing ligands are polymerized or copolymerized into resins containing ligands in the main or side chains of polymers. The mechanism of chelating resin adsorbing metal ions is that the functional atoms on the resin react with metal ions to form a stable structure similar to small molecular chelates, while the adsorption mechanism of ion exchange resin is electrostatic. Therefore, compared with ion exchange resins, chelating resins have stronger binding force and higher selectivity with metal ions. Chelating resin in biological applications: mainly used to remove divalent cations in enzymes and other solutions, can also be used to reduce the concentration of calcium and magnesium ions in the auxotroph.
