In the past, most cell-proliferation studies have used radioactive thymidine as an incorporated label to give evidence of DNA replication. Recently, a less hazardous technique has been developed using bromodeoxyuridine (BrdU), a thymidine analog, in lieu of a radioactive reagent. (1) BrdU is incorporated into proliferating cells (S-phase) much in the same way as radioactive thymidine, but is then detected by a monoclonal anti-BrdU antibody, and revealed using a highly sensitive streptavidin- biotin staining system. BrdU has proven useful for proliferative studies of normal and neoplastic tissues both in vivo and in vitro.
Catalog #B2851
The BrdU staining system uses a biotinylated monoclonal anti-BrdU, thus eliminating the need for a species-specific secondary antibody. As a result, BrdU labeling can be performed in rats and mice without problems of crossreactivity or spurious staining.
Streptavidin-peroxidase is used as a signal generator for the BrdU system. Diaminobenzidine (DAB) in the presence of hydrogen peroxide is used as a chromogen, staining BrdU-incorporated nuclei dark brown.
This kit also contains four BrdU control slides for the convenience of the investigator four unstained positive controls.
