HeLa human cervical epithelial carcinoma cell line was stained with Rat Anti-Human Mesothelin Monoclonal Antibody (Catalog # MAB32652, filled histogram) or isotype control antibody (Catalog # MAB006, open histogram), followed by Phycoerythrin-conjugated Anti-Rat IgG F(ab')₂Secondary Antibody (Catalog # F0105B).

Mesothelin Specificity is Shown by Flow Cytometry in Knockout Cell Line

Mesothelin knockout HeLa human cervical epithelial carcinoma cell line was stained with Rat Anti-Human Mesothelin Monoclonal Antibody (Catalog # MAB32652, filled histogram) or isotype control antibody (Catalog # MAB006, open histogram) followed by Phycoerythrin-conjugated Anti-Rat IgG F(ab')2 Secondary Antibody (Catalog # F0105B). No staining in the Mesothelin knockout HeLa cell line was observed. View our protocol for Staining Membrane-associated Proteins.

Human Mesothelin ELISA Standard Curve.

Recombinant Human Mesothelin protein was serially diluted 2-fold and captured by Mouse Anti-Human Mesothelin Monoclonal Antibody (Catalog # MAB32655) coated on a Clear Polystyrene Microplate (Catalog # DY990). Rat Anti-Human Mesothelin Monoclonal Antibody (Catalog # MAB32652) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Applications for Human Mesothelin Antibody

Application

Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

ELISA

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human Mesothelin Monoclonal Antibody (Catalog # MAB32655).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human Mesothelin DuoSet ELISA Kit (Catalog # DY3265) for convenient development of a sandwich ELISA or the Human Mesothelin Quantikine ELISA Kit (Catalog # DMSLN0) for a complete optimized ELISA.

Background: Mesothelin

Mesothelin is a 40 kDa glycosylphosphatidylinositol-anchored glycoprotein that is expressed on mesothelial cells in the pleura, pericardium and peritoneum and overexpressed in mesotheliomas and ovarian or pancreatic adenocarcinoma. Mesothelin is a product of the CAK-1 gene, which also encodes megakaryocyte-potentiating factor (MPF). Mature human mesothelin shares 60% amino acid identity with either mouse or rat mesothelin. Two variant forms exist; variant 1 has an eight amino acid (1 kDa) insertion and is rarely expressed, while variant 2 is a truncated form secreted in the majority of ovarian cancers but rarely found in normal individuals.
