Chemical Name: N,N,N',N'-Tetrakis(2-pyridylmethyl)ethylenediamine

Biological Activity

Heavy metal chelator. Reacts with both Zn-proteome and Zn-metallothionein (MT) in LLC-PK1 cells; acts as an intracellular chelator of proteomic Zn2+. Activity decreases intracellular zinc levels, and induces apoptosis in HeLa and cultured human retinal pigment epithelium (RPE) cells. Cell permeable.

Technical Data

Soluble to 25 mM in DMSO and to 100 mM in ethanol
>98 %
Store at +4°C
