Biological Activity: 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 Fe2+, Cd2+, Co2+, Ni2+, Zn2+, etc. Phen green SK (PGSK) diacetate chelates Fe2+, 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[1][2][3].
