H2DCFDA (solution)

Guide (The following is our recommended protocol. This protocol is only a guide and should be modified according to your specific needs).
1. Working Solution Preparation
The corresponding stock solution can be diluted according to the actual situation. Note that if the solvent is DMSO, the cytotoxicity of DMSO must be considered, and a solvent control should be prepared; if the solvent is pure water, the working solution needs to be filtered and sterilized before adding cells.
2. Cell staining (suspended cells)
2.1 Collect cells by centrifugation and wash twice with PBS for 5 minutes each time.
2.2 Add 1 mL of dye working solution and incubate at room temperature for 5-30 minutes.
2.3 Centrifuge at 400 g for 3-4 minutes and discard the supernatant.
2.4 Add PBS to wash the cells twice, 5 minutes each time.
2.5 Resuspend the cells in 1 mL of serum-free medium or PBS and observe using a fluorescence microscope or flow cytometer.
3. Cell staining (adherent cells)
3.1 Culture the adherent cells on a sterile coverslip.
3.2 Remove the coverslip from the culture medium and remove the excess culture medium.
3.3 Add 100 μL of dye working solution, gently shake to completely cover the cells, and incubate for 5-30 minutes.
3.4 Aspirate the dye working solution, wash 2-3 times with culture medium, 5 minutes each time, and observe using a fluorescence microscope or flow cytometer.
Note: If flow cytometry is required, the cells need to be digested with trypsin and resuspended before staining.
