Descrição geral
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]
Aplicação
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]
Ações bioquímicas/fisiológicas
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]
