Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation,
Specificity / Sensitivity
Mesothelin (D4X7M) Rabbit mAb recognizes endogenous levels of total mesothelin protein. The antibody recognizes both uncleaved (full-length) and cleaved forms of mesothelin, but does not detect the cleaved fragment corresponding to megakaryocyte-potentiating factor (MPF).
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly577 of human mesothelin protein.
Western blot analysis of extracts from various cell lines using Mesothelin (D4X7M) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower).
Western blot analysis of extracts from OVCAR8 cells, untreated (-) or PNGase F-treated (+), using Mesothelin (D4X7M) Rabbit mAb. Results demonstrate change in electrophoretic mobility of mesothelin following deglycosylation by PNGase F.
Immunoprecipitation of mesothelin from OVCAR8 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is Mesothelin (D4X7M) Rabbit mAb. Western blot analysis was performed using Mesothelin (D4X7M) Rabbit mAb. Mouse Anti-rabbit IgG (Conformation Specific) (L27A9) mAb #3678 was used as a secondary antibody.
The MSLN gene encodes a 69 kDa precursor protein that is proteolytically cleaved to yield Megakaryocyte Potentiating Factor (MPF) and a GPI-anchored membrane protein termed mesothelin (1). Expression of (cleaved) mesothelin is largely confined to mesothelial cells of normal pleura, pericardium, and peritoneum, but has been reported to be overexpressed in some cancers, including mesothelioma, and some pancreatic and ovarian adenocarcinomas (1,2). Although suggested to be involved in cell adhesion, the physiological functions of mesothelin have not been determined. It is known, however, that mesothelin can be shed from the cell surface following cleavage by TNF-α converting enzyme. Research studies show that serum levels of mesothelin are markedly increased in patients with mesothelioma and ovarian cancer (1), suggesting that serum mesothelin levels may have utility as a cancer biomarker (1-3).
