Our Abpromise guarantee covers the use of ab1831 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
WB Use at an assay dependent concentration. Predicted molecular weight: 38 kDa.
IHC-P Use at an assay dependent concentration.
IHC-Fr Use at an assay dependent concentration.

Flow Cyt Use 1µg for 106 cells.

ab170191 - Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.



  • Function
    Repair polymerase. Conducts "gap-filling" DNA synthesis in a stepwise distributive fashion rather than in a processive fashion as for other DNA polymerases. Has a 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity.
  • Sequence similarities
    Belongs to the DNA polymerase type-X family.
  • Domain
    Residues 239-252 form a flexible loop which appears to affect the polymerase fidelity.
  • Post-translational
    Methylation by PRMT6 stimulates the polymerase activity by enhancing DNA binding and processivity.
  • Cellular localization
    Nucleus, Cytoplasm

  • Overlay histogram showing Jurkat cells stained with ab1831 (red line). The cells were fixed with 4% paraformaldehyde and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab1831, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

Thank you for your enquiry. This antibody was purified by protein A chromatography, and the concentration is approximately 100 ug/ml. If you have any additional questions, please contact us again.

I'm sorry to hear you are having problems with ab1831 in IHC. The fact that the antibody still works in WB suggests that the antibody is fine but that there is a component in the IHC protocol which is damaged, there could potentially be many "ingre...
