| Product Name | TSQ Zinc Ion Fluorescent Probe |
| Catalog No. | RESK-0524 |
| Description | TSQ is a membrane-permeant fluorescent probe for cellular zinc ions and can be used for intracellular imaging of zinc proteins (λmax ~470 nm). TSQ binds Zn2+ even in the presence of Ca2+ and Mg2+, generating blue fluorescence (Ex/Em = 334/495 nm). |
| Intended Use | Intracellular imaging of zinc ions and zinc proteins in cells. For research use only. |
| Principle / Technology | Cell-permeant probe that selectively complexes Zn2+ in the presence of Ca2+ and Mg2+, yielding a blue fluorescent signal. |
| Detection Method | Fluorescence imaging / fluorescence measurement (blue fluorescence) |
| Sample Type | Cultured cells (intracellular zinc imaging) |
| Performance Range / Specifications | Appearance: off-white solid CAS NO.: 109628-27-5 Formula: C17H16N2O3S Molecular weight: 328.39 Ex/Em: 355/499 nm (product specification); blue fluorescence at Ex/Em = 334/495 nm with λmax ~470 nm reported for intracellular imaging Solubility: soluble in DMSO |
