Product Information
Description: PGSK diacetate (5/6-mixture) is a metal ion-sensitive fluorescent probe that can penetrate cell membranes. PGSK diacetate can react with a variety of metal ions, including Fe2+, Cd2+, Co2+, Ni2+, Zn2+, etc. 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 PGSK diacetate are 507/532 nm, respectively.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
