The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 39 kDa (predicted molecular weight: 32 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
FunctionMembrane-anchored forms may play a role in cellular adhesion. Megakaryocyte-potentiating factor (MPF) potentiates megakaryocyte colony formation in vitro.
Tissue specificityExpressed 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 diseaseNote=Antibodies against MSLN are detected in patients with mesothelioma and ovarian cancer.
Sequence similaritiesBelongs to the mesothelin family.
Post-translational modificationsBoth 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.
Cellular localizationSecreted and Cell membrane. Golgi apparatus.
