Application Abreviews Notes
WB 1/500. Detects a band of approximately 174 kDa (predicted molecular weight: 174 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC 1/100 - 1/250.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function
      Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks.
    • Sequence similarities
      Belongs to the type II topoisomerase family.
    • Post-translational
      Phosphorylation has no effect on catalytic activity.
    • Cellular localization
      Cytoplasm. Nucleus > nucleoplasm. Generally located in the nucleoplasm.
