EGTA-AM

EGTA-AM (EGTA Acetoxymethyl ester) 是一种钙离子螯合剂， 是一种膜渗透形式的 EGTA，是早发型子痫前期和晚发性子痫前期的代谢生物学标志物。

DMNPE-4 AM-caged-calcium, a photolabile analogue of EGTA, is a highly efficient Ca2+-selective cage. At pH 7.2 and pH 7.4, its Kd for Ca2+ is measured at 48 nM and 19 nM, respectively. Upon photolysis, DMNPE-4 AM-caged-calcium exhibits a decreased affinity for Ca2+ (~2 nM Kd).
