Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 69 kDa.Can be blocked with Mesothelin peptide (ab134675).
  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function

      Membrane-anchored forms may play a role in cellular adhesion.
      Megakaryocyte-potentiating factor (MPF) potentiates megakaryocyte colony formation in vitro.
    • Tissue specificity

      Expressed in lung. Expressed at low levels in heart, placenta and kidney. Expressed in mesothelial cells. Highly expressed in mesotheliomas, ovarian cancers, and some squamous cell carcinomas (at protein level).
    • Involvement in disease

      Note=Antibodies against MSLN are detected in patients with mesothelioma and ovarian cancer.
    • Sequence similarities

      Belongs to the mesothelin family.
    • Post-translational

      Both MPF and the cleaved form of mesothelin are N-glycosylated.
      Proteolytically cleaved by a furin-like convertase to generate megakaryocyte-potentiating factor (MPF), and the cleaved form of mesothelin.

    I have good news today.

    We now added the blocking peptide for ab92347 to our catalog and it is available for purchase.


    https://www.abcam.com/index.html?datasheet=134675 (or use the following: https://www.abcam.com/index.html?datasheet=134675).

    It is notin stock at the moment but has a lead time of 1-2 weeks if ordered now.

    I hope this information is helpful and wish a nice weekend.

    Thank you for your reply.

    I have to confirm that we do not have this peptide in our catalog at the moment. We are trying toadd this toour catalog but Ido not have any estimationwhen this will be available for your customer.

    Your customer might want to get it synthesized from a other company.

    As for the negative control, any peptide with a different sequence can be used. Your customer most probably already has a unrelated peptide in the freezer.

    I am sorry I could not be of more help on this occasion.
