TSQ
Based on 9 publication(s) in Google Scholar
TSQ is a cytosolic zinc ion fluorescence probe that is membrane permeable and can be used for intracellular imaging of zinc proteins. TSQ is a bidentate ligand, utilizing quinoline and sulfonamide nitrogens to coordinate Zn2+; it binds to Zn22+ in a 2:1 ligand to metal ratio (Ex/Em = 334/495 nm).

Guide (The following is our recommended protocol. This protocol is for reference only and should be modified according to your specific needs).
1. Solution preparation[4]
1.1 Preparation of stock solution
Solvent: DMSO
Concentration: 1-30 mM (optimized according to the experiment).
Storage: Store at -20°C or -80°C in dark after aliquoting. Avoid repeated freezing and thawing.
1.2 Preparation of working solution
Dilute to 1-30 μM with DPBS or other buffers.
Note: The working solution should be prepared and used immediately. Keep it away from light.
2. Cell staining
2.1 Cells are grown on glass coverslips coated with Collagen, rat tail (HY-NP010).
2.2 Rinsed three times with Dulbecco's phosphate buffered saline.
2.3 30 μM TSQ in DPBS, mix well and incubate at 37°C for 30 minutes.
2.4 After the stained cells are rinsed three times with DPBS.
2.5 Fluorescence microscopy detection (Ex/Em = 334/495 nm).
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

TSQ intracellular Zn2+ probe detection of temporal changes in Zn2+ release from ZnO and H-ZnO in cells. White arrow indicates fluorescence signal of intracellular zinc ion release. To further clarify intracellular Zn2+ release, the TSQ (30 µM; 30 min) probe was used to detect fluorescence in L929 cells. After 15 min of ZnO treatment, intracellular Zn2+ levels significantly increased and continued to rise over time.
