Application Abreviews Notes
ICC/IF Use at an assay dependent concentration. PubMed: 19376971
WB 1/500 - 1/1000. Detects a band of approximately 65 kDa (predicted molecular weight: 48 kDa).
ELISA 1/5000.
IHC-P 1/50 - 1/100.


  • 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.

  • All lanes : Anti-Cyclin B1 (phospho S126) antibody (ab55184) at 1/500 dilution

    Lane 1 : extracts from NIH/3T3 cells treated with EGF (200ng/ml, 15mins).
    Lane 2 : extracts from NIH/3T3 cells treated with EGF (200ng/ml, 15mins); ab36621 pre-incubated with the immunising phosphopeptide.

    Predicted band size : 48 kDa
    Observed band size : 65 kDa (why is the actual band size different from the predicted?)
  • Immunohistochemical analysis of Cyclin B1 (phospho S126) expression in paraffin embedded human lung carcinoma tissue using ab55184 at 1/50 dilution (left). Right hand panel represents a negative control where ab55184 was pre-incubated with the immunising (blocking) phosphopeptide.
