BCECF is a pH-sensitive fluorescent dye and can be used to monitor cellular pH ratiometrically. BCECF allows measurements in the physiological pH range 6.0–8.0. Excitation ratio: 490/440 nm; Emission intensity: 535 nm.

Fully treated cells show hydrogenosomes with an electron-dense deposit which aggregates to a variable extent.The staining is seen in the interior of hydrogenosomes in some instances. It is also observed by microscopy that the K/H ionophor nigericin does not inhibit hydrogenosomal loading with BCECF. The pH-sensitive fluorescent dyes to measure cytosolic pH.
1.Prepare a 2 to 20 mM stock solution of BCECF in DMSO.
2.Prepare a 5-50 µM BCECF dye-loading solution in buffer solutions (HHBS or PBS). 3. Add 1000 µL/well (6-well plate),100 µL/well (96-well plate) or 25 µL/well (384-well plate) BCECF dye-loading solution into the cell plate. 4. Incubate the dye-loading plate in a cell incubator for 30-60 minutes. 5. Wash and replace the dye-loading solution with buffers. 6. Run the pH assay by monitoring the fluorescence at Ex/Em = 490/535 nm or 430/535 nm for ratio measurements.
