| PGSK diacetate (5/6-mixture)
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. |
| Dextran-Rhodamine B
Dextran-Rhodamine B (RB-Dextran) is a fluorescent marker made by combining rhodamine B fluorescent dye and dextran polysaccharide through a specific chemical reaction. RB-Dextran is a red fluorescent modified dextran polysaccharide formed by chemically labeling rhodamine B onto dextran molecules, which can be used in cell tracing, biofluid dynamics research and other fields, and its fluorescent properties can be used to track the distribution and metabolism of dextran in organisms and other processes. |
| N-Succinimidyl 6-(2,4-Dinitroanilino)hexanoate
N-Succinimidyl 6-(2,4-Dinitroanilino)hexanoate, the DNP-X acid modified by succinimidyl ester, is an amine-reactive building block for developing a probe, which can be recognized by anti-DNP antibodies. |
