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

Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 150 kDa (predicted molecular weight: 145 kDa).
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
Flow Cyt Use at an assay dependent concentration.
ICC/IF 1/100 - 1/250.
  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      Acts as a transcriptional repressor. Interacts with MXI1 to repress MYC responsive genes and antagonize MYC oncogenic activities. Also interacts with MAD-MAX heterodimers by binding to MAD. The heterodimer then represses transcription by tethering SIN3A to DNA. Acts as a corepressor for REST.
    • Sequence similarities

      Contains 3 PAH (paired amphipathic helix) domains.
    • Post-translational

      SUMO1 sumoylated by TOPORS. Probably desumoylated by SENP2.
    • Cellular localization

      Nucleus. Nucleus > nucleolus. Recruited to the nucleolus by SAP30L.

      Lane 4: Jurkat cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab129087 observed at 150 kDa. Red - loading control, ab8245, observed at 37 kDa.
      ab129087 was shown to recognize mSin3A when mSin3A knockout samples were used, along with additional cross-reactive bands. Wild-type and mSinA knockout samples were subjected to SDS-PAGE. ab129087 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/10000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

    • Immunocytochemistry/Immunofluorescence analysis of MCF7 (Human breast adenocarcinoma cell line) labeling mSin3A with Purified ab129087 at 1/500 dilution (5 µg/ml). Cells were fixed with 4% PFA and permeabilized with 0.1% tritonX-100. ab150077 Goat anti rabbit IgG(Alexa Fluor® 488) at 1/1000 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI. PBS was used instead of the primary antibody as the negative control.

    • Flow Cytometry analysis of MCF-7 (human breast carcinoma) cells labeling mSin3A with purified ab129087 at 1/250 dilution(10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488)(1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.
