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

Application Abreviews Notes
Protein Array Use at an assay dependent concentration.
IHC-P Use a concentration of 0.5 - 1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB Use a concentration of 1 - 2 µg/ml. Predicted molecular weight: 50 kDa.


  • Function

    Regulates progression through early mitosis by inhibiting the anaphase promoting complex/cyclosome (APC). Binds to the APC activators CDC20 and FZR1/CDH1 to prevent APC activation. Can also bind directly to the APC to inhibit substrate-binding.
  • Sequence similarities

    Contains 1 F-box domain.
    Contains 1 IBR-type zinc finger.
  • Developmental stage

    Accumulates in late G1 phase, levels rise during S phase and drop in early mitosis.
  • Domain

    The C-terminal region is required for inhibition of APC activity.
  • Post-translational

    Phosphorylation by CDK2 and subsequently by PLK1 triggers degradation during early mitosis through ubiquitin-mediated proteolysis by the SCF ubiquitin ligase complex containing the F-box protein BTRC. This degradation is necessary for the activation of APC in late mitosis and subsequent mitotic progression.
  • Cellular localization

    Nucleus. Cytoplasm. Cytoplasm > cytoskeleton > spindle. In interphase, localizes in a punctate manner in the nucleus and cytoplasm with some perinuclear concentration. In mitotic cells, localizes throughout the cell, particularly at the spindle.

  • ab215765 was tested in protein array against over 19000 different full-length human proteins.
    Z- and S- Score: The Z-score represents the strength of a signal that a monoclonal antibody (MAb) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target.
    A MAb is specific to its intended target if the MAb has an S-score of at least 2.5. For example, if a MAb binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that MAb to protein X is equal to 29.
