Product description

SPQ is a fluorescent chloride indicator. Its fluorescence is rapidly quenched by chloride in vitro. It has been used to assess voltage-sensitive chloride transport in placental microvillus vesicles. It has also been used to continuously quantify intracellular calcium efflux induced by parathyroid hormone, forskolin, and phorbol 12-myristate 13-acetate (PMA) in isolated human erythrocytes.In addition, SPQ has been used to determine the type of ion conductance induced by the cystic fibrosis transmembrane conductance regulator (CFTR) in HEK293 cells expressing pTrial10-CRTR2. SPQ displays excitation maxima of 320 and 350 nm and an emission maximum of 445 nm.
