Phen Green SK diacetate

Phen green SK (PGSK) diacetate is a fluorescent heavy metal indicator that reacts with a variety of metal ions, including Fe2+, Cd2+, Co2+, Ni2+, and Zn2+. PGSK diacetate displays excitation/emission maxima of 507/532 nm, respectively, and fluorescence is quenched upon interaction with metal ions. It has been used to quantify iron in isolated rat hepatocytes, characterize metal-ion selectivity of divalent metal-ion transporter 1 (DMT1), and monitor copper transport across P. sativum chloroplast membranes.Formal Name: 3',6'-bis(acetyloxy)-2',7'-dichloro-3-oxo-N-1,10-phenanthrolin-5-yl-spiro[isobenzofuran-1(3H),9'-[9H]xanthene]-5-carboxamide.
