Applications:

  • EDTA, disodium salt, dihydrate, for molecular biology is extensively used as a chelator of divalent cations such as Ca2+.
  • EDTA (Ethylenediaminetetraacetic acid) is a chelating agent, a general chemical, and a sequestrant. 
  • In molecular biology applications,addition of EDTA minimizes the impact of metal ion contaminants.
  • It is used to facilitate enzymatic reactions that could be inhibited by heavy metal traces.
  • It a inhibits enzymes, such as metalloproteases, which require divalent cations for activity.
  • EDTA, disodium salt, dihydrate, for molecular biology is an inhibitor of Calpain.
