6-Carboxyfluorescein ≥98% (by HPLC) fluorescent pH indicator
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
