N,N,N′,N′-Tetrakis(2-pyridylmethyl)ethylendiamin

Heavy metal chelator.


A cell permeable and extremely high-affinity chelator of heavy metals, yet with low affinity for Mg²⁺ and Ca²⁺.


Lipid-soluble, crossing both natural and artificial membranes. TPEN can be used in conjunction with QUIN 2 or QUIN 2/AM to reduce heavy-metal quenching of QUIN 2 fluorescence in cells. Ion specificity is Zn²⁺>Fe²⁺>Mn²⁺>>Ca²⁺=Mg²⁺. Complex with Fe²⁺ catalyses superoxide dismutation.


Soluble in dimethyl formamide, DMSO, 100% ethanol or methanol.
