Our Abpromise guarantee covers the use of ab7957 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use a concentration of 5 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
IHC-Fr Use at an assay dependent concentration.
IP Use at an assay dependent concentration.
WB Use at an assay dependent concentration. Detects a band of approximately 58 kDa (predicted molecular weight: 49 kDa).


  • FunctionEssential for the control of the cell cycle at the G2/M (mitosis) transition.
  • Sequence similaritiesBelongs to the cyclin family. Cyclin AB subfamily.
  • Developmental stageAccumulates steadily during G2 and is abruptly destroyed at mitosis.
  • Post-translational
    Ubiquitinated by the SCF(NIPA) complex during interphase, leading to its destruction. Not ubiquitinated during G2/M phases.
  • Cellular localizationCytoplasm. Nucleus. Cytoplasm > cytoskeleton > centrosome.

  • IHC image of Cyclin B1 staining in human cervix formalin fixed paraffin embedded tissue section, performed on a Leica Bond 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 ab7957, 5µg/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.
