    제품 종류
  • SPQ (Full chemical name: 6-methoxy-N-(3- sulfopropyl)quinolinium) (purity > 95% by HPLC)
    • Catalog Number: 52010

      • The fluorescence of SPQ (full chemical name: 6-methoxy-N-(3-sulfopropyl)quinolinium) is specifically quenched by chloride via collision. Therefore, chloride concentration is measured by monitoring the degree of fluorescence decrease. The dye can be loaded into cells by hypotonic shock.

      White solid soluble in H2O and DMSO. Store at 4 ° C. Protect from light, especially when in solution.

      λex＼λ em = 344nm＼443nm. e (344 nm, H2O) = 37,000.

      C9H15NO4S. Mwt: 281.
