一般描述

乙二胺四乙酸(EDTA)是一种取代二胺,被广泛应用于家用和工业领域。EDTA螯合金属二价阳离子,如钙、镁、锌、铜、锰,形成金属-EDTA络合物。它适用于清洁产品和洗涤剂配方。在纸和纸浆工业中,EDTA可减少金属离子对漂白的不利影响。它作为抗菌剂能够除去外膜中的钙和镁二价阳离子,并导致膜脂多糖的损失,使细菌对杀菌剂敏感。游离EDTA对哺乳动物的繁殖和发育具有不利影响。EDTA可以螯合导致动脉粥样硬化、癌症和心脏病的沉积物中的离子。它能够减少自由基反应和氧化过程,进而帮助克服细胞膜损伤。它可以与钙结合并降低癌症患者患高钙血症的风险。跨膜乙二胺四乙酸铵梯度法有助于药物递送,从而增强药物保留和治疗效果并降低细胞毒性水平。

应用

EDTA已被用于:
  • 作为合成输卵管液培养物1(SOFC1)培养基的补充剂,用于胚胎培养
  • 孵育EpCAM+细胞和异硫氰酸荧光素(FITC)标记抗体,用于细胞分选分析
  • 预处理脾脏树突细胞的单细胞悬浮液,用于磁珠细胞分选
