Our Abpromise guarantee covers the use of ab28739 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 a concentration of 4 - 8 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB Use a concentration of 2.5 µg/ml. Predicted molecular weight: 40,25 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.



  • Immunohistochemical staining of paraffin embedded human kidney with ab28739 at 4-8 ug/ml. Arrows indicate postive staining of epithelial cells of the renal tube.
  • Anti-l-Myc antibody (ab28739) at 2.5 µg/ml + Human foetal kidney lysate

    HRP conjugated anti-Rabbit IgG 1: 50,000 - 100,000

    Predicted band size: 40,25 kDa
    Observed band size: 23 kDa
    why is the actual band size different from the predicted?

Thank you for your reply. For the c-myc antibody, I suggest that you look at ab56 or ab11917. A positive control would be ab7914. Please let me know which would be best for you. I also hope that you are able to find the replacement l-myc that was sent and are able to run successful experiments with it. Let me know if you have any questions or concerns.

Thank you for contacting Abcam.

I am sorry to hear of the continued disappointing results from ab28739. I would be glad to send you a different antibody against l-myc or to issue you a credit note for the purchase. Please let me know what you decide.

If you have any questions do not hesitate to contact me.

To my knowledge, customized protocols were not used in for this product. I've linked our standard western blotting protocol here: https://www.abcam.com/index.html?pageconfig=resource&rid=13045 In our published sample, Anti-l-Myc antibody (ab28739)was used at 2.5 µg/ml. With a secondary HRP conjugated anti-Rabbit IgG used at 1: 50,000 - 100,000. However, because your positve controls have also failed, and since I have spoken with you about your protocols, I believe that the issue lies in the product itself. I would like to send you a free of charge replacement for ab28739 Anti-l-Myc antibody. Due to the holiday season, I would like to make sure that if I sent a replacement someone would be around to recieve it. Would it be alright to send this week (we have 1 in the U.S now), or would it be better if we held off the delivery until after the New Year? I look forward to your reply.
