Broxuridine, BUdR

Bromodeoxyuridine (5-bromo-2'-deoxyuridine, BrdU, BUdR, BrdUrd, broxuridine) is a synthetic nucleoside analogue with a chemical structure similar to thymidine. BrdU is commonly used to study cell proliferation in living tissues[1] and has been studied as a radiosensitizer[2] and diagnostic tool in people with cancer.[3] During S phase of the cell cycle (when DNA replication occurs), BrdU can be incorporated in place of thymidine in newly synthes...
