实验概要The method provides a protocol and tips for BrdU staining in tissue sections.Bromodeoxyuridine (5-bromo-2-deoxyuridine, BrdU) is a synthetic analogue of the nucleoside thymidine. It is incorporated into replicating DNA in dividing cells and can be subsequently detected by anti-BrdU antibodies.Immunostaining of the labeled cells is a standard IHC/ICC procedure but requires a step to denature DNA, allow......阅读全文
