5-Carboxyfluorescein ≥98% (by HPLC) fluorescent pH indicator
5-Carboxyfluorescein
5-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) = 492/514 nm
- pKa 6.5
- Extinction Coefficient (ε) 82,000 (pH 9)
- Yellow orange solid soluble in pH>6 water
- Store at 4°C and protect from light, especially in solution
