Detection of Human Mesothelin by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Human Mesothelin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3265) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Mesothelin at approximately 69 kDa (as indicated). This experiment was conducted under reducing conditions and Immunoblot Buffer Group 8.

Background: Mesothelin

Mesothelin is a 40 kDa, 292 amino acid (aa) GPI-linked glycoprotein found on normal mesothelial cells. It is also highly expressed in pancreatic, gastric and ovarian carcinomas. Mesothelin is synthesized as a preproprotein with a carboxy-terminal hydrophobic proregion that is removed when a GPI-anchor is added. The N-terminal prosegment is cleaved by furin to release a 33 kDa soluble protein that is also known as megakaryocyte potentiating factor (MPF). The membrane bound portion of Mesothelin can also be shed and is detectable in sera. Within the region used as the immunogen, human Mesothelin shares approximately 58% amino acid sequence identity with the mouse or rat protein.
