溶于碱溶液,几乎不溶于水。EGTA是最为被广泛使用的钙离子选择性的螯合剂,用于在镁存在下,测定钙。它与钙离子形成的复合物比与镁离子形成的复合物要稳定100,000倍,被用来制备钙缓冲液和控制钙离子的浓度。容量分析及光度分析中测量微量金属的络合剂、掩蔽剂。也可滴定钡、锶、铜、镁和锌。 RNA逆转录酶中RNA的脱氧测序缓冲器组分
EGTA (Ethylene Glycol Tetraacetic Acid) is a useful chemical in a variety of buffers. EGTA is a chelating agent that can be used for the determination of calcium in the presence of magnesium since EGTA has greater specificity for calcium ions. EGTA is also useful in ELISA reactions as an inhibitor of alkaline phosphatase activity. EGTA has also been shown to activate Ca2+-stimulated ATPase in rat liver plasma membranes and induce apoptosis in PC12 cells. It also inhibits the zinc-dependent endopeptidases, MMPs (Matrix metalloproteinases).
