General description

乙二胺四乙酸（EDTA）是一种亲水金子螯合剂，将金属离子转化成无活性，环化金属复合物。因此，它在工业中可以用于解决金属污染物。

Application

乙二胺四乙酸可用作：
  • 可用作标记缓冲液组分，在细胞裂解{155)过程中用于冲洗
  • 调查木瓜酶酵素对于伤口清创和其他皮肤问题的效果
  • 预处理之后，流式细胞仪收获大鼠血管平滑肌细胞

Biochem/physiol Actions

乙二胺四乙酸（EDTA）无法被胃肠道吸收。EDTA钠静脉注射导致低血钙手足抽搐。它通常用于血浆或分子诊断，和钙鳌合。EDTA可用作血液细胞计数和细胞形态分析中抗凝聚剂。
