BCECF is a neutral lipophilic form of bis-carboxyfluorescein which diffuses freely through the plasma membrane.
The fluorescence intensity of BCECF is dependent upon the pH with a maximum response at an excitation of [lambda]=535 nm (F1), while at [lambda]=490 nm (F2), the intensity is independent of pH.
To determine pHi, a non-carbonate solution and BCECF
, an intracellular fluorescent dye, were used and the light density was found using a spectroflourometer.
