Our Abpromise guarantee covers the use of ab3608 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.
WB Use a concentration of 0.1 - 0.3 µg/ml. Detects a band of approximately 150 kDa (predicted molecular weight: 136 kDa).Can be blocked with Human SAP130 peptide (ab22952).


  • Function

    Acts as a transcriptional repressor. May function in the assembly and/or enzymatic activity of the mSin3A corepressor complex or in mediating interactions between the complex and other regulatory complexes.
  • Tissue specificity

    Expressed in various cancer cell ines.
  • Sequence similarities

    Belongs to the SAP130 family.
  • Domain

    The N-terminus may interact with a transcriptional coactivator.
    The C-terminus may interact with HDAC-dependent and HDAC-independent corepressors.

  • Anti-SAP130 antibody (ab3608) at 0.1 µg/ml + HeLa cells, nuclear lysate at 30 µg

    Predicted band size: 136 kDa
    Observed band size: 150 kDa
    why is the actual band size different from the predicted?

  • IHC image of ab3608 staining in human normal cervix formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. 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 ab3608, 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.
