General description

Ethylenediaminetetraacetic acid (EDTA) is a chelator of metal ions. It is a substituted diamine, which has antibacterial activity. EDTA removes the undesirable effects of ferric, cupric and manganic ions in bleaching. It prevents cellular division, chlorophyll synthesis and algal biomass production. EDTA is an inhibitor of metalloprotease. It has anticoagulant property.

Application

Ethylenediaminetetraacetic acid tetrasodium salt dihydrate has been used:
  • as a chelating agent to isolate human endometrial stem cell/stromal cells (hEnSCs) from menstrual blood
  • as a chelator in animal and testicular cell isolation
  • as a chelator for the culture of neural stem cells

Biochem/physiol Actions

Ethylenediaminetetraacetic acid (EDTA) is used to eliminate enzyme inhibition by traces of heavy metals, and to inhibit enzymes that require divalent cations as cofactors.
