Our Abpromise guarantee covers the use of ab55179 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
ELISA 1/10000.
IHC-P Use at an assay dependent concentration.
WB 1/500 - 1/1000. Detects a band of approximately 30 kDa (predicted molecular weight: 18 kDa).


  • FunctionAccelerates programmed cell death. Binding to the apoptosis repressors Bcl-X(L), BHRF1, Bcl-2 or its adenovirus homolog E1B 19k protein suppresses this death-promoting activity. Does not interact with BAX.
  • DomainIntact BH3 motif is required by BIK, BID, BAK, BAD and BAX for their pro-apoptotic activity and for their interaction with anti-apoptotic members of the Bcl-2 family.
  • Cellular localizationEndomembrane system. Around the nuclear envelope, and in cytoplasmic membranes.

    Lane 1 : extracts from HepG2 cells.
    Lane 2 : extracts from HepG2 cells, incubated with the immunising phosphopeptide.

    Predicted band size : 18 kDa
    Observed band size : 30 kDa (why is the actual band size different from the predicted?)
