Our Abpromise guarantee covers the use of ab54740 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 a concentration of 1 - 5 µg/ml.
Flow Cyt Use 1µg for 106 cells. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
IHC-P Use a concentration of 10 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • Function
    Binds to proliferating cell nuclear antigen. Might affect PCNA interaction with some CDK (cell division protein kinase) complexes; stimulates DNA excision repair in vitro and inhibits entry of cells into S phase.
  • Sequence similarities
    Belongs to the GADD45 family.

  • Western blot against tagged recombinant protein immunogen using ab54740 GADD45A antibody at 1ug/ml. Predicted band size of immunogen is 36 kDa.

    This antibody has only been tested in WB against the recombinant fragment used as immunogen. We have no data on the detection of endogenous protein.

  • IHC image of GADD45A staining in human kidney formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab54740, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
  • Overlay histogram showing Jurkat cells stained with ab54740 (red line). The cells were fixed with 80% methanol (5 min) 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 (ab54740, 1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was an anti-mouse Alexa Fluor® 488 (ab150113) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

Customer reviews and Q&As

Thank you for your reply.

I am inclined to believe that the issue is with the samples themselves. It is very unusual for 3 different antibodies to detect bands mainly above 100kDa when the expected MW should be around 25kDa. How long ar...

Thank you for your reply.

I was wondering if you would clarify a few additional points for me.

How were the samples prepared? How much is loaded on the gel?

What is the molecular weight of each band in the ladd...
