General description

Ethylenediaminetetraacetic acid (EDTA) is a hydrophilic metal chelating agent that transforms metal ions into inactive, cyclic metal complexes. Hence, it has industrial application for resolving metal contamination.[1]

Application

Ethylenediaminetetraacetic acid has been used:
  • as a component of labeling buffer, which is used in the washing step during cell fractionation{155)
  • for investigating the effect of papain enzyme on wound debridement and other skin issues[2]
  • for harvesting rat arterial smooth muscle cell after its pre-treatment for its use in flow cytometry analysis[3]

Biochem/physiol Actions

Ethylenediaminetetraacetic acid (EDTA) is not easily administered by the gastrointestinal tract. Intravenous administration of sodium EDTA results in hypocalcemic tetany.[4] It is generally useful in plasma or molecular diagnostics and acts by chelating calcium. EDTA serves as an anticoagulant for haematological cell counting and cell morphological analysis.[5]

    Because both endothelin-1 (ET-1) and angiotensin II (AngII) are independent mediators of arterial remodeling, we sought to determine the role of ET receptor inhibition in AngII-accelerated atherosclerosis and aortic aneurysm formation. We administered saline or AngII and/or bosentan, an endothelin
