TSQ
Cellular Zinc Fluorescent Sensor
TSQ is a membrane-permeable fluorescent probe designed for the detection of zinc ions within cells, specifically targeting the cytosolic compartment. It exhibits a fluorescence emission maximum at approximately 495 nm when excited at 334 nm, enabling effective intracellular imaging of zinc-containing proteins. TSQ forms a complex with Zn2+ in the presence of Ca2+ and Mg2+, resulting in a distinctive blue fluorescence signal, making it a valuable tool for research applications involving cellular zinc dynamics and metalloprotein studies.
