Phen green SK (PGSK) diacetate (PGSK diacetate (5/6-mixture)) is a metal ion-sensitive fluorescent probe that can penetrate cell membranes. Phen green SK (PGSK) diacetate can react with a variety of metal ions, including Fe 2+, Cd 2+, Co 2+, Ni 2+, Zn 2+, etc. Phen green SK (PGSK) diacetate chelates Fe 2+, resulting in fluorescence quenching, which can be restored when a membrane-permeable chelator is added, thereby reflecting the changes in the intracellular chelatable iron pool. The excitation/emission maxima of Phen green SK diacetate are 507/532 nm, respectively .
