5-Bromo-2-deoxyuridine (BrdU) is an analog of thymidine, and can be incorporated into the newly synthesized DNA of replicating cells (S-phase cells). BrdU is a commonly used in the detection of proliferating cells in living tissues. It works by substituting for thymidine during DNA replication and incorporating itself into the newly synthesized DNA (during S-phase). Antibodies specific for BrdU can then be used to detect the incorporated chemical, thus indicating cells that were actively replicating their DNA. Because BrdU can replace thymidine during the S phase of cell division, it can cause mutations.
Example protocol
PREPARATION OF STOCK SOLUTION
Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.
BrdU DMSO stock solution:
Make 1 - 10 mM DMSO stock solution by dissolving the BrdU in DMSO. Note: The DMSO stock solution is good for 6 months if stored at -20 °C.
PREPARATION OF WORKING SOLUTION
BrdU working solution:
Make 5-20 µM working solution in buffer of your choice. Note: BrdU working solution should be used promptly and be made fresh every time.
SAMPLE EXPERIMENTAL PROTOCOL
- Pellet cells by centrifugation and resuspend the cells in completed growth media. Adherent cells in culture may be stained in situ on cover slips or in the cell culture wells.
- Add BrdU working solution and incubate it for 60 minutes to overnight as a guide. Note: The optimum incubation time will depend upon cell type and goal of the experiment.
- Fix cells with 70 - 80% alcohol or acid-ethanol for 20 - 30 minutes.
- Wash with PBS (3 times, 2 min. each).
- Proceed with immunocytochemical staining techniques.
