Descrição

Descrição geral

Lipid-soluble heavy metal chelator that crosses artificial and natural membranes. Auxiliary reagent in certain techniques used for measuring free Ca²⁺ in cells. Has an extremely high affinity for heavy metals but a low affinity for Ca²⁺ and Mg²⁺. Induces DNA fragmentation when chelated with Zn²⁺ and causes apoptosis in thymocytes. Strips heavy metals from liposome-trapped QUIN 2. Shown to be useful in extracting Aβ depostis from Alzheimer′s disease brain tissue.

Induces DNA fragmentation when chelated with Zn²⁺ and induces apoptosis in thymocytes. Strips heavy metals from liposome-trapped QUIN 2 (Cat. No. 551826).

Aplicação

• 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).

Advertência

Toxicity: Standard Handling (A)

Reconstituição

Following reconstitution, aliquot and freeze (-20°C) under an inert gas. Alternately, acidify (pH ≤3) with HCl for long term storage. Stock solutions are stable for up to 3 months at -20°C.
