The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.3 - 1 µg/ml. Detects a band of approximately 70 kDa (predicted molecular weight: 69 kDa). An approximately 70 kDa band was observed in Human Placenta lysates. An additional band of unknown identity was also consistently observed at 150 kDa. This band was successfully blocked by incubation with the immunizing peptide.
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.
