Application Abreviews Notes
  • Application notes
    IHC-P: Use at an assay dependent dilution.

  • Target

    • Function

      May play a role in tumor angiogenesis.
    • Tissue specificity

      Expressed in tumor endothelial cells but absent or barely detectable in normal endothelial cells. Expressed in metastatic lesions of the liver and during angiogenesis of corpus luteum formation and wound healing. Expressed in vascular endothelial cells of malignant tumors but not in normal blood vessels. Expressed in stromal fibroblasts.

    Thank you for contacting us yesterday and alerting us to the problem you are experiencing with the anti-TEM1 antibody (ab67273). We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

    As discussed over the phone, all of our products are covered by the Abpromise guarantee. This stipulates that if you find the product is not functioning as indicated on the datasheet of the product and the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the antibody. As you mentioned that you were not able to test the antibody at the time of purchase I would be willing to extend this guarantee period for you as a gesture of good will. More information on the Abpromise guarantee can be found from the following link:


    When you are ready to share the data you have gathered with this antibody please do let me know and I can look into this further. I have attached a questionnaire to this email to provide a guideline as to the information which is usually very useful in investigating this case internally and initiate additional testing where necessary.

    You also mentioned over the phone that your colleague had had similar problems with the
    anti-TEM1 antibody (ab67275). If you could provide any information as to the results generated with this antibody I would be very interested to know.

    I look forward to receiving your reply.

    Thank you for contacting us.

    Lab has confirmed that they have tested this antibody in western blotting and Immunohistochemistry only - no further tests other than these has been done. I am sorry the data we have is already published on the datasheet - we are unable to provide any more tested data.

    I hope this information is nevertheless helpful to you. Please do not hesitate to contact us if you need any more advice or information.
