  • RelevanceThe immunocytochemical detection of bromodeoxyuridine (BrdU) incorporated into DNA is a powerful tool to study the cytokinetics of normal and neoplastic cells. In vitro or in vivo labeling of tumor cells with the thymidine analogue BrdU and the subsequent detection of incorporated BrdU with specific anti-BrdU monoclonal antibodies is an accurate and comprehensive method to quantitate the degree of DNA-synthesis. BrdU is incorporated into the newly synthezised DNA of S-phase cells may provide an estimate for the fraction of cells in S-phase. Also dynamic proliferative information such as the S-phase transit rate and the potential doubling time can be obtained, by means of bivariate BrdU/DNA flow cytometric analysis.

Anti-BrdU antibody - Proliferation Marker images

  • ab1893 used in IP.
  • ab1893 at a 1/50 dilution staining rat brain tissue sections by IHC-P. The incubation time with the primary antibody was overnight at 4°C. This image shows double-staining by polyclonal sheep BrdU (labeled with Cy3 - red) and nestin 401v (labeled with Alexa Fluor® 488 - green). The detection of proliferative (BrdU-positive) astrocytes (some of them express also nestin, which demonstrates that they are reactive and of lower differentiation compared with later stages of reactive astrocytes) within the rat striatum 6 days after striatal neurotoxic lesion (by quolinic acid).

    Tissue culture cells were labelled prior to transplantation and then identified in in vivo tissue using ab1893 sheep polyclonal BrdU antibody (10ug/ml incubated overnight at room temperature) with a TRITC conjugated secondary antibody.

Thank you for your patience in this matter.

I have been trying to determine if any of our BrdU antibodies are only specific to BrdU or not and it seems that most of them have some sort of cross reactivity with either ErdU or ...
