Product Summary
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.

The recovery of EMMPRIN spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 102 91-111
EDTA Plasma (n=4) 98 90-110
Heparin Plasma (n=4) 96 85-104
Serum (n=4) 100 90-111
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.

Background: EMMPRIN/CD147
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.

    Assay Procedure
    Refer to the product for complete assay procedure.

    Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
    1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
    2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

    3. 50 µL Assay Diluent
    4.   Add 50 µL of Assay Diluent to each well.

    5. 50 µL Standard, Control, or Sample
    6.   Add 50 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
    7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

    8. 200 µL Conjugate
    9.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
    10.   Aspirate and wash 4 times.

    11. 200 µL Substrate Solution
    12.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

    13. 50 µL Stop Solution
    14.   Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
