Thermo Scientific™ N,N,N',N'-Tetrakis-(2-pyridylmethyl)ethylenediamine (TPEN) is a cell-permeable, high-affinity chelator of transition and heavy metals such as zinc (Zn²⁺), iron (Fe²⁺/Fe³⁺), and copper (Cu²⁺).
Due to its exceptional metal-binding selectivity, TPEN is widely used in cell biology, biochemistry, and neurochemistry to regulate or deplete intracellular metal ion concentrations without disrupting overall cell membrane integrity.
Its versatility and permeability make it a valuable tool in metal-dependent enzyme studies, oxidative stress assays, apoptosis signaling, and metalloprotein regulation research.
Key Features
- High Metal Affinity: Efficient chelation of divalent metal ions (Zn²⁺, Fe²⁺, Cu²⁺, Mn²⁺).
- Cell-Permeable: Enables intracellular chelation in live-cell experiments.
- Research-Grade Purity: ≥95% (as confirmed by supplier’s CoA).
- Reversible Chelator: Allows dynamic control of intracellular metal ion concentrations.
- Applications: Metal homeostasis, apoptosis signaling, and oxidative stress studies.
- Stable Powder Form: Supplied as a high-purity solid for ease of handling and reproducibility.
- Research Use Only (RUO): For laboratory applications; not for therapeutic use.
