Anti-BrdU antibodies are useful reagents for the flow cytometric detection of bromodeoxyuridine (BrdU), a nucleoside analog commonly used to study active DNA synthesis. BrdU can be incorporated in place of thymidine during the S phase of the cell cycle, making it a chemical marker for cells actively synthesizing DNA. BrdU-labeling and detection is used in studying cell proliferation, tumor progression, and microbial metabolism. Examine the supplier's provided validation data when comparing BrdU antibodies for flow cytometry. Also look for application-specific recommendations, such as dilutions, protocols, sample types, and other helpful usage notes.
