  • General notes
    Recently XRCC-1 has been shown to be physically associated with other DNA repair enzymes, including PARP, DNA ligase III and DNA polymerase beta.



Our Abpromise guarantee covers the use of ab9147 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 a concentration of 2 - 6 µg/ml.
WB 1/1000 - 1/10000. Detects a band of approximately 90 kDa (predicted molecular weight: 70 kDa).
ICC/IF 1/200 - 1/500.


  • Function
    Corrects defective DNA strand-break repair and sister chromatid exchange following treatment with ionizing radiation and alkylating agents.
  • Sequence similarities
    Contains 2 BRCT domains.
  • Post-translational
    Phosphorylation of Ser-371 causes dimer dissociation. Phosphorylation by CK2 promotes interaction with APTX and APLF.
  • Cellular localization
    Nucleus. Accumulates at sites of DNA damage.

    Observed band size: 76,90 kDa
    why is the actual band size different from the predicted?

    Detection: ECL.
  • ab9147 staining human HeLa cells by ICC/IF.  Cells were PFA fixed and permeabilized in 0.5% Triton X100 prior to blocking in 5% BSA for 30 minutes at 20°C.  The primary antibody was diluted 1/200 and incubated with the sample for 1 hour at 20°C.  A Cy3® conjugated donkey anti-rabbit antibody diluted 1/400 was used as the secondary.

Thank you for the details in which you have provided. Since you got absolutely no signal even with the HeLa nuclear extract (what is recommended as a positive control) it's definitely telling me that something is wrong with the batch/vial that you received. My suggestion would be to try increasing the concentration of the primary antibody, but since you're not even seeing any background I really don't think that would help. Anyway, I'm sending a replacement vial to you on order# 54735 and you should receive it tomorrow. Please let me know how it works out for you and if you have any further questions.
