The Quantikine Human EMMPRIN Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human EMMPRIN in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains NS0-expressed recombinant human EMMPRIN and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human EMMPRIN 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 ocurring EMMPRIN.
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.
Cell Culture Supernates, Saliva, Urine, Human Milk
Serum, EDTA Plasma, Heparin Plasma
The recovery of EMMPRIN spiked to levels throughout the range of the assay in various matrices was evaluated.

To assess the linearity of the assay, samples containing high concentrations of EMMPRIN were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
The name EMMPRIN reflects this proteins extracellular metalloproteinase inducer activity. It is a cell surface protein with two extracellular Ig domains, a transmembrane domain, and a cytoplasmic domain. Its expression is often elevated in human tumor cells, which in turn promotes MMP-1, MMP-2 and MMP-3 production in melanoma cells and MMP-2 and MMP-9 production in breast cancer cells. It interacts with several types of molecules such as integrins, caveolin-1 and MCT1. TRA-1-85 is an epitope within EMMPRIN.
