6-Methoxy-N-(3-sulphopropyl)quinolinium (SPQ)
SPQ is a blue fluorescent dye (Ex/Em 344/443 nm) that is specifically quenched by chloride via collision (KSV=118 M-1). Therefore, chloride concentrations can be measured by moniotiring the degree of fluorescence decrease. The dye can be loaded into cells by hypotonic shock.

- Store at 4°C. Protect from light, especially in solution.
- λEx/λEm= 344nm / 443nm
