Our Abpromise guarantee covers the use of ab4288 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
IHC-P Use at an assay dependent concentration. This antibodoidy stained islets but not in ducts and acini of Human normal pancreas. However, in pancreatic ductal adenocarcinoma staining was in the ducts and acini.
WB Use at an assay dependent dilution. Detects a band of approximately 60 kDa (predicted molecular weight: 43 kDa).


  • Function
    E3 ubiquitin-protein ligase that may play a role in controlling cell proliferation.
  • Tissue specificity
    Widely expressed (at protein level). In normal pancreas, expressed in islets, but not in ducts, nor in acini (at protein level).
  • Pathway
    Protein modification; protein ubiquitination.
  • Sequence similarities
    Contains 1 PA (protease associated) domain.
    Contains 1 RING-type zinc finger.
  • Domain
    The RING-type zinc finger domain is required for E3 ligase activity.
  • Post-translational
  • Cellular localization
    Endoplasmic reticulum membrane. Golgi apparatus membrane. Late endosome membrane. Lysosome membrane. Nucleus inner membrane. Under certain conditions, relocalizes to recycling endosomes and to the inner nuclear membrane.

Thank you very much for contacting us regarding ab4288. I am very sorry to hear that you are experiencing difficulty with this antibody. Where did you place the tag on RNF13? It is possible that the tag is interfering with your ability to detect the overexpressed RNF13 especially if the tag is on the C-terminus. This is also theoretically possible if the tag is on the N-terminus but is not as easy to explain. I would recommend moving the epitope tag or using a different tag and then see what result you have. The predicted molecular weight of the unprocessed precursor RNF13 is 42.8 kDa. If it is processed then the MW will be slightly lower. While the antibody has worked for us in a peptide ELISA, we have not observed a band in WB so I cannot tell you the actual detected MW. As you may know, ab4288 is one of our Fast-track antibodies and it is not yet fully characterized. We cannot guarantee that the antibody will work in any application other than ELISA against the immunizing peptide and therefore we are unable to offer a refund if the antibody does not work in your application. However, Fast-Track antibodies are offered at a reduced price. We would be very grateful for you if you could submit a review via the product datasheet. We have a very special Feedback reward system for Fast-track products: we would greatly appreciate your feedback on this antibody, whether positive or negative. We will award 950 Abpoints to the first researcher who sends us positive feedback (including an image and details of materials & methods). Conclusive negative feedback that leads us to withdraw the antibody will also be rewarded with 950 Abpoints. Other useful positive and negative feedback will be rewarded with 50 Abpoints. To find out more about our Loyalty Scheme and Abpoints, please visit our website and look at Your Account panel (left bottom section on our home page) or the Earn Abpoints section on the product datasheet. All awards are subject to approval by Abcam scientists and provision of suitable data. Please submit feedback to fast-track@abcam.com and would be grateful if you could also attach your Western blot image. We hope to receive your review very shortly. Thank you for your time and your effort,
