It is brominated derivative of deoxyuridine that acts as an antimetabolite or base analog, substituting for thymidine in DNA. It can induce DNA mutations in the same way as 2-aminopurine It is used in the detection of proliferating cells in living tissues, as it can be incorporated into the newly synthesized DNA of replicating cells, then detected using antibodies."}]
