Guide (The following is the experimental plan we recommend. This plan serves only as a reference guide. The specific operations should be adjusted according to your actual needs.)
1. Preparation of PKH 26 working solution
1.1 Preparation of stock solution
Prepare a 1 mM stock solution using DMSO
1.2 Preparation of PKH 26 working solution
Dilute the stock solution in serum-free cell culture medium or PBS to obtain a working solution of 5-10 μM.
Note: Please adjust the concentration of the PKH 26 working solution as needed
2. Cell staining
2.1 Suspended cells (6-well plate)
a. Centrifuge at 4°C for 1000g for 3-5 minutes, discard the supernatant, wash twice with PBS, each time for 5 minutes. The cell density is 1×106/mL.
b. Add 1 mL of the working solution, incubate at room temperature for 10-45 minutes.
c. Centrifuge at 400g for 4-5 minutes at 4°C, discard the supernatant.
d. Wash twice with PBS, each time for 5 minutes.
e. Resuspend the cells in serum-free cell culture medium or PBS. Observe with a fluorescence microscope or flow cytometer.
2.2 Attached cells
a. Cultivate attached cells on a sterile cover glass.
b. Remove the cover glass from the culture medium and aspirate the excess medium.
c. Add 100 μL of the working solution, gently shake to fully cover the cells, incubate at room temperature for 5-30 minutes.
d. Wash twice with the culture medium, each time for 5 minutes. Observe with a fluorescence microscope or flow cytometer.
