Our Abpromise guarantee covers the use of ab37003 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
IP Use at an assay dependent concentration.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 140 kDa (predicted molecular weight: 123 kDa).

Abcam recommends using 3% milk as the blocking agent.

ICC/IF Use a concentration of 1 µg/ml.
ChIP Use at an assay dependent concentration. PubMed: 20452320


  • Relevance
    The protein encoded by this gene is a member of the SWI/SNF family of proteins. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. Two transcript variants encoding different isoforms have been found for this gene.

  • All lanes : Anti-SMARCA1 antibody (ab37003) at 1 µg/ml (blocked with 3% milk)

    Lane 1 : Jurkat nuclear extract lysate (ab14844)
    Lane 2 : HEK293 (Human embryonic kidney cell line) Nuclear Lysate
    Lane 3 : SHSY5Y Whole Cell Lysate

    Lysates/proteins at 20 µg per lane.

    Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 123 kDa
    Observed band size : 140 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 70 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 16 minutes
  • ICC/IF image of ab37003 stained human HeLa cells. The cells were PFA fixed (10 min), permabilised in PBS-T (20 min) and incubated with the antibody (ab37003, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

  • SMARCA1 was immunoprecipitated using 0.5mg Jurkat whole cell extract, 5µg of Rabbit polyclonal to SMARCA1 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Jurkat whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab37003.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 105kDa: SMARCA1.
