アプリケーション Abreviews 特記事項
WB 1/2000 - 1/10000. Detects a band of approximately 210 kDa (predicted molecular weight: 183 kDa).
IP Use at 2-5 µg/mg of lysate.
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • 機能
    Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Indirectly ivolved in vitamin D-coupled transcription regulation via its association with the WINAC complex, a chromatin-remodeling complex recruited by vitamin D receptor (VDR), which is required for the ligand-bound VDR-mediated transrepression of the CYP27B1 gene.
  • 配列類似性
    Belongs to the type II topoisomerase family.
  • 翻訳後修飾
    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • 細胞内局在
    Cytoplasm. Nucleus > nucleolus.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human ovarian carcinoma tissue labelling Topoisomerase II beta with ab72334 at 1/200 (1µg/ml). Detection: DAB.
  • All lanes : Anti-Topoisomerase II beta antibody (ab72334) at 0.04 µg/ml

    Lane 1 : Whole cell lysate from Hela cells at 50 µg
    Lane 2 : Whole cell lysate from Hela cells at 15 µg
    Lane 3 : Whole cell lysate from Hela cells at 5 µg
    Lane 4 : Whole cell lysate from 293T cells at 50 µg

    Developed using the ECL technique.

    Predicted band size: 183 kDa
    Observed band size: 210 kDa (why is the actual band size different from the predicted?)

    Exposure time: 30 seconds
  • Immunoprecipitation/ Western Blot of Topoisomerase II beta.
    Lane 1: ab72334 at 3µg/mg whole cell lysate.
    Lane 2: Control IgG.
    ab72334 at 0.1µg/ml for WB.
    Whole cell lysate from Hela cells at 1mg for IP, 20% of IP loaded.
    Chemiluminescence with an exposure time of 30 seconds.
  • IHC image of ab72334 staining in human normal tonsil formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab72334, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
