BackgroundBromodeoxyuridine (BrdU) is a thymidine analog which is selectively incorporated into the DNA of proliferating cells to provide a marker for the DNA being replicated during the S-phase of the cell cycle. The number of proliferating cells can then be quantified in cell lysates, cell suspensions or tissue sections using an antibody specific for BrdU. Previous methods of detecting DNA included the use of [3H]-thymidine, which would be incorporated into the DNA and the replicated DNA could then be quantified by autoradiography or scintillation counting. These methods are more difficult and require more cleanup due to the radioactive material. An immunohistochemical or immunocytochemical assay provides a much simpler and cleaner method for detecting replicating DNA in cells.

ProductUnstained, formalin fixed, BrdU labeled MCF7 (human breast carcinoma derived) cells grown on glass slides.

ApplicationsThe BrdU labeled MCF7 cells can be used as control for immunohistochemical or immunocytochemical staining procedures. Optimal concentrations of antibodies applied to these cell preparations should be evaluated by serial dilutions. About 50% of the cells are labeled with BrdU and therefore the slides provide both a positive and negative control.

评估细胞周期进程在许多研究领域都非常重要，传统的方法是将[3H]胸腺嘧啶核苷掺入S期细胞，然后通过闪烁计数或放射自显影来定量[3H], 以此来检测细胞增殖，但该技术流程耗时且费力，还有许多限制因素比如同位素污染处理和设备昂贵等问题。
