BCECF is ideal for measuring changes ± 1 pH unit around pH 7, because it is a dual-excitation ratiometric pH indicator with a pKa of ~6.98. pH measurements with BCECF are made by determining the pH-dependent ratio of emission intensity (detected at 535 nm) when the dye is excited at ~490 nm versus the emission intensity when excited at its isobestic point of ~440 nm.
