Mesothelin, also known as MSLN or MPF is a protein that in humans is encoded by the MSLN gene. This gene is mapped to 16p13.3. This gene encodes a precursor protein that is cleaved into two products, megakaryocyte potentiating factor and mesothelin. Megakaryocyte potentiation factor functions as a cytokine that can stimulate colony formation in bone marrow megakaryocytes. Mesothelian is a glycosylphosphatidylinositol-anchored cell-surface protein that may function as a cell adhesion protein. This protein is overexpressed in epithelial mesotheliomas, ovarian cancers and in specific squamous cell carcinomas. Sample Type: Cell culture supernates, serum, plasma (heparin, EDTA) and urine Intended Use: For quantitative detection of human Mesothelin in cell culture supernates, serum, plasma (heparin, EDTA), saliva and urine. Sensitivity: <10pg/ml Range: 156-10,000pg/ml Specificity: Natural and recombinant human Mesothelin Test Principle: This human Mesothelin BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for Mesothelin has been precoated onto 96-well plates. Standards(NSO, E296-G580) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Mesothelin is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human Mesothelin amount of sample captured in plate.
