Ethylenediaminetetraacetic acid (EDTA) sodium hydrate 是一种金属螯合剂 (与包括钙在内的二价和三价金属阳离子结合), 具有抗高钙血症和抗凝血活性。Ethylenediaminetetraacetic acid sodium hydrate 可减少金属离子催化的蛋白质氧化损伤，并维持蛋白质纯化过程中的还原环境，常用作蛋白质的纯化和储存。Ethylenediaminetetraacetic acid sodium hydrate 还可减少二硫键的形成。
Ethylenediaminetetraacetic acid (EDTA) sodium hydrate is a metal chelators (binds to metal divalent and trivalent cations including calcium), which shows activities of anticoagulant and anti-hypercalcemic. Ethylenediaminetetraacetic acid sodium hydrate decreases the metal ion-catalyzed oxidative damage to proteins, and allows maintenance of reducing environment during protein purification. Ethylenediaminetetraacetic acid sodium hydrate can also decrease the formation of disulfide bonds[1][2][3].
