6-Carboxyfluorescein ≥98% (durch HPLC) fluoreszierender pH-Indikator
6-Carboxyfluorescein

6-Carboxyfluorescein has a pKa of 6.5 and can be used as a pH sensor. The excitation spectrum of the dye responds to pH similarly to that of BCECF. Carboxyfluorescein can also be used as a tracer dye. The dye is membrane-impermeant and can be loaded into cells by microinjection or scrape loading.


  • λEx/λEm (pH 9) = 495/519 nm
  • pKa 6.5
  • Yellow orange solid soluble in water (pH>6), DMF or DMSO
  • Store at 4°C and protect from light
