说明

一般說明

脂溶性重金属螯合剂，可穿过人工膜和天然膜。某些技术中用于测量细胞内游离Ca²⁺水平的辅助试剂。也可用于从阿尔茨海默’病脑组织中提取Aβ淀粉样沉积物。对重金属有极高的亲和力，但对Ca²⁺和Mg²⁺的亲和力较低。与Zn²⁺螯合时诱导DNA断裂，并诱导胸腺细胞凋亡。从脂质体捕获的QUIN 2（目录号551826）中去除重金属。

應用

• Poly(ADP-ribosyl)ation of p53 contributes to TPEN-induced neuronal apoptosis.: This study investigates the role of poly(ADP-ribosyl)ation of the tumor suppressor protein p53 in neuronal apoptosis induced by TPEN, highlighting mechanisms of cell death in neurodegenerative diseases (Kim HL et al., 2015).


• Essential role of p53 in TPEN-induced neuronal apoptosis.: This article explores the critical involvement of the p53 protein in apoptosis initiated by TPEN in neuronal cells, offering insights into potential therapeutic targets for neuroprotection (Ra H et al., 2009).


• Clioquinol induces autophagy in cultured astrocytes and neurons by acting as a zinc ionophore.: Demonstrates how Clioquinol, similar to TPEN, functions as a zinc ionophore to induce autophagy, particularly in neurological contexts, which may be relevant for understanding TPEN′s mechanisms (Park MH et al., 2011).

警告

毒性：标准处理（A）

重構

复溶后，等分并在惰性气体下冷冻（-20°C）。或者，用盐酸酸化（pH ≤3），以便长期贮藏。贮备溶液在-20°C下可稳定保存至多3个月。
