• Product nameAnti-EMSY antibody
    See all EMSY primary antibodies
  • Description
    Goat polyclonal to EMSY
  • SpecificityThis antibody detects a band of the same size by Western blot as ab123, which was raised with a recombinant fragment of EMSY with no sequence in common with the immunogen for this antibody (and was raised 7 years previous to this antibody). This confirms that the band detected is EMSY.
  • Tested applicationsICC/IF, WB, ICCmore details

ICC Use at an assay dependent dilution.


  • RelevanceEMSY binds BRCA2 within a region (exon 3) deleted in cancer. EMSY is capable of silencing the activation potential of BRCA2 exon 3, associates with chromatin regulators HP1 and BS69, and localizes to sites of repair following DNA damage. Its levels are amplified in breast and ovarian cancer.
  • Cellular localizationNuclear. Localizes to DNA damage markers in irradiated cells; suggesting that it participates in the DNA repair process.

    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 141 kDa
    Observed band size : 100 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 37 kDa,70 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 2 minutes

    Western blot of EMSY on MCF-7 cell lysate.

    Lane 1: ab4579 at 1ug/ml with 2% BSA blocking.

    Lane 2: ab4579 at 1ug/ml with 3% milk blocking.

    Lane 3: ab123 at 1ug/ml with 2% BSA blocking.

    Variability in the size at which EMSY runs by Western blot has been experienced with different protein marker systems. EMSY has been observed to run at between 115 and 150kD (even though the predicted size is 141kD). However, that the same size band is detected by both ab123 and ab4579 (raised with immunogens of different sequence) confirms the specificity of these antibodies.

     Lane 1 & 2 - Exposure time: 2 min.

    Lane 3 - Exposure time: 2 sec.
