    Verwendungszweck
    The AssayMax™ Human Recoverin ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for detection of human recoverin in plasma, serum, tissue extracts, and cell culture samples. This assay employs a quantitative sandwich enzyme immunoassay technique that measures human recoverin in approximately 5 hours. A polyclonal antibody specific for human recoverin has been pre-coated onto a 96-well microplate with removable strips. Recoverin in standards and samples is sandwiched by the immobilized polyclonal antibody and biotinylated polyclonal antibody specific for human recoverin, 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.

    Aufbereitung der Reagenzien

    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 Recoverin Standard: Reconstitute the 80 ng of Human Recoverin Standard with 4 mL of MIX Diluent to generate a 20 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 (20 ng/mL) 2-fold with MIX Diluent to produce 10, 5, 2.5, 1.25, 0.625, and 0.313 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. 4 Standard Point Dilution [Human Recoverin] (ng/mL) P1 1 part Standard (20 ng/mL) 20.0 P2 1 part P1 + 1 part MIX Diluent 10.0 P3 1 part P2 + 1 part MIX Diluent 5.0 P4 1 part P3 + 1 part MIX Diluent 2.5 P5 1 part P4 + 1 part MIX Diluent 1.25 P6 1 part P5 + 1 part MIX Diluent 0.625 P7 1 part P6 + 1 part MIX Diluent 0.313 P8 MIX Diluent 0.0 Biotinylated Human Recoverin Antibody (50x): Spin down the antibody briefly and dilute the desired amount of the antibody 50-fold with MIX Diluent. The undiluted antibody should be stored at -20 °C. Wash Buffer Concentrate (20x): If crystals have formed in the concentrate, mix gently until the crystals have completely dissolved. Dilute the Wash Buffer Concentrate 20-fold with reagent grade water. SP Conjugate (100x): Spin down the SP Conjugate briefly and dilute the desired amount of the conjugate 100-fold with MIX Diluent. The undiluted conjugate should be stored at -20 °C.

    Probennahme
    Plasma: Collect plasma using one-tenth volume of 0.1 M sodium citrate as an anticoagulant. Centrifuge samples at 3000 x g for 10 minutes and collect plasma. Samples can be stored at -20 °C or below for up to 3 months. Avoid repeated freeze-thaw cycles. Serum: Samples should be collected into a serum separator tube. After clot formation, centrifuge samples at 3000 x g for 10 minutes and remove serum. Samples can be stored at -20 °C or below for up to 3 months. Avoid repeated freeze-thaw cycles. Tissue: Extract tissue samples with 50 mM phosphate-buffered saline ( pH 7.4) containing 1 % Triton X-100. Centrifuge at 14000 x g for 20 minutes.

    Testdurchführung

    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 Recoverin Standard or sample per 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 Recoverin 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 2 hours. Wash the microplate as described above. 5 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 per well. Gently tap plate to thoroughly coat the wells. Break any bubbles that may have formed. Incubate for 15 minutes or till 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.

    Ergebnisberechnung
    • 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.
