Is BrdU (Bromodeoxyuridine) myelotoxic?

No, BrdU (Bromodeoxyuridine) is not myelotoxic at labeling concentrations. This makes it a safe and effective tool for identifying and monitoring the proliferation of cancer cells in-vivo. However, BrdU’s use for radiosensitizing is limited because it becomes myelosuppressive at radiosensitizing concentrations.
