Ethylenediaminetetraacetic acid

Ethylenediaminetetraacetic acid (EDTA) is a chelating agent commonly used in protein purification, to decreases the metal ion-catalyzed oxidative damage to proteins, and allows maintenance of reducing environment during protein purification and to inhibit protease activity. It can also decrease the formation of disulfide bonds and can also inhibit complement activation; protein protection in some immunoassays
