体外研究 (In Vitro) | Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs). 1. Prepare a 2-20 mM stock solution of BCECF in DMSO and store at -20℃.2. Prepare a 5-50 μM BCECF dye-loading solution in buffer solutions (Hepes, pH 7.4 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 about 30minutes.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.
