    This product is sold as crude ascites fluid so we estimate the IgG concentration ~1-3mg/ml.



Our Abpromise guarantee covers the use of ab3362 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
WB Use at an assay dependent concentration. Detects a band of approximately 73 kDa (predicted molecular weight: 69 kDa). PubMed: 18490724
IHC-Fr Use at an assay dependent concentration.

Acetone fixation was used.

Flow Cyt Use at an assay dependent concentration. PubMed: 18490724
IHC-P Use at an assay dependent concentration. Antigen retrieval is not essential but may optimise staining.

One hour primary antibody incubation was used.


  • 功能Membrane-anchored forms may play a role in cellular adhesion.
    Megakaryocyte-potentiating factor (MPF) potentiates megakaryocyte colony formation in vitro.
  • 组织特异性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).
  • 疾病相关Note=Antibodies against MSLN are detected in patients with mesothelioma and ovarian cancer.
  • 序列相似性Belongs to the mesothelin family.
  • 翻译后修饰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.

    Lysates/proteins at 10 µg per lane.

    Goat Anti-Mouse IgG H&L (HRP) preadsorbed (ab97040) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 69 kDa
    Observed band size : 73 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 15 kDa,44 kDa. We are unsure as to the identity of these extra bands.
