Product Summary
The Quantikine Human Mesothelin Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Mesothelin in cell culture supernates, serum, plasma, saliva, and urine. It contains NS0-expressed recombinant human Mesothelin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Mesothelin showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring Mesothelin.

Precision
Intra-Assay Precision (Precision within an assay)
Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays)
Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Linearity
To assess the linearity of the assay, samples containing high concentrations of Mesothelin were serially diluted Calibrator Diluent to produce samples with values within the dynamic range of the assay.

- Background
- Mesothelin/MPF
- Mesothelin is a glycosylphosphatidylinositol-anchored glycoprotein that is expressed on mesothelial cells in the pleura, pericardium and peritoneum and overexpressed in mesotheliomas and ovarian or pancreatic adenocarcinomas. 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.
