BrdU ELISA kits are assays designed to detect the synthetic nucleotide analogue of thymidine, bromodeoxyuridine. BrdU is used in the detection of proliferating cells and as a marker of cell injury. It can replace thymidine during the S phase of the cell cycle and become incorporated into newly replicated cells. It is also used in environmental microbiology to observe the utilization of carbon substrates for microbial growth.
