A brief introduction to EDTA disodium salt dihydrate

6381-92-6

　　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. Also used to facilitate enzymatic reactions that could be inhibited by heavy metal traces. It also inhibits enzymes, such as metalloproteases, which require divalent cations for activity.
