    Fonction
    The AssayMax™ Human Proteinase 3 ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for detection of PR3 in human plasma, serum, saliva, urine, milk, CSF, and cell culture samples. This assay employs a quantitative sandwich enzyme immunoassay technique that measures PR3 in approximately 4 hours. A polyclonal antibody specific for PR3 has been pre- coated onto a 96-well microplate with removable strips. PR3 in standards and samples is sandwiched by the immobilized antibody and biotinylated polyclonal antibody specific for PR3, which is recognized by a streptavidin- peroxidase conjugate. All unbound material is washed away and a peroxidase enzyme substrate is added. The color development is stopped and the intensity of the color is measured.

    Préparation des réactifs

    Freshly dilute all reagents and bring all reagents to room temperature before use. MIX Diluent Concentrate (10x): If crystals have formed in the concentrate, mix gently until the crystals have completely dissolved. Dilute the MIX Diluent Concentrate 10-fold with reagent grade water. Store for up to 30 days at 2-8 °C. Human Proteinase 3 Standard: Reconstitute the 180 ng of Human Proteinase 3 Standard with 1.5 mL of MIX Diluent to generate a 120 ng/mL standard stock solution. Allow the standard to sit for 10 minutes with gentle agitation prior to making dilutions. Prepare duplicate or triplicate standard points by serially diluting from the standard stock solution (120 ng/mL) 2-fold with MIX Diluent to produce 60, 30, 15, 7.5, 3.75, and 1.875 ng/mL solutions. MIX Diluent serves as the zero standard (0 ng/mL). Any remaining stock solution should be frozen at -20 °C and used within 30 days. Avoid repeated freeze-thaw cycles.

    Procédure de l'essai

    Prepare all reagents, standard solutions, and samples as instructed. Bring all reagents to room temperature before use. The assay is performed at room temperature (20-25 °C). Remove excess microplate strips from the plate frame and return them immediately to the foil pouch with desiccants inside. Reseal the pouch securely to minimize exposure to water vapor and store in a vacuum desiccator. Add 50 l of Human Proteinase 3 Standard or sample to each well. Gently tap plate to thoroughly coat the wells. Break any bubbles that may have formed. Cover wells with a sealing tape and incubate for 2 hours. Start the timer after the last addition. Wash five times with 200 l of Wash Buffer manually. Invert the plate each time and decant the contents, hit 4-5 times on absorbent material to completely remove the liquid. If using a machine, wash six times with 300 l of Wash Buffer and then invert the plate, decanting the contents, hit 4-5 times on absorbent material to completely remove the liquid. Add 50 l of Biotinylated Human Proteinase 3 Antibody to each well. Gently tap plate to thoroughly coat the wells. Break any bubbles that may have formed. Cover wells with a sealing tape and incubate for 1 hour. Wash the microplate as described above. Add 50 l of Streptavidin-Peroxidase Conjugate to each well. Gently tap plate to thoroughly coat the wells. Break any bubbles that may have formed. Cover wells with a sealing tape and incubate for 30 minutes. Turn on the microplate reader and set up the program in advance. Wash the microplate as described above. Add 50 l of Chromogen Substrate to each well. Gently tap plate to thoroughly coat the wells. Break any bubbles that may have formed. Incubate for 25 minutes or until the optimal blue color density develops. Add 50 l of Stop Solution to each well. The color will change from blue to yellow. Gently tap plate to ensure thorough mixing. Break any bubbles that may have formed. Read the absorbance on a microplate reader at a wavelength of 450 nm immediately. If wavelength correction is available, subtract readings at 570 nm from those at 450 nm to correct optical imperfections. Otherwise, read the plate at 450 nm only. Please note that some unstable black particles may be generated at high concentration points after stopping the reaction for about 10 minutes, which will reduce the readings. 6

    Calcul des résultats
    • Calculate the mean value of the duplicate or triplicate readings for each standard and sample.
    • To generate a standard curve, plot the graph using the standard concentrations on the x-axis and the corresponding mean 450 nm absorbance (OD) on the y-axis. The best-fit line can be determined by regression analysis using log-log or four-parameter logistic curve-fit.
    • Determine the unknown sample concentration from the standard curve and multiply the value by the dilution factor.

    Sujet
    Proteinase 3 (PR3, PRTN3), a neutral serine proteinase, is also known as myeloblastin, Wegener autoantigen, azurophil granule protein 7, and neutrophil protease p29 (1). PR3 is produced and packaged into azurophil granules during neutrophil differentiation. The mature PR3 consists of 228 amino acids and has a molecular mass of approximately 29 kDa (2). PR3 degrades connective-tissue proteins, particularly elastin, fibronectin, type IV collagen, and laminin (3). It has potent antimicrobial activity and is involved in a variety of immune defense reactions that contribute to the destruction of ingested microorganisms (4).
