    原理
    The AssayMaxTM Human Antithrombin III ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for detection of ATIII in human plasma and serum samples. This assay employs a quantitative competitive enzyme immunoassay technique that measures human ATIII in approximately 3 hours. A polyclonal antibody specific for human ATIII has been pre-coated onto a 96- well microplate with removable strips. ATIII in standards and samples is competed with a biotinylated human ATIII protein sandwiched by the immobilized antibody and streptavidin-peroxidase (SP) 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.

    试剂准备

    Freshly dilute all reagents and bring all reagents to room temperature before use. EIA Diluent Concentrate (10x): If crystals have formed in the concentrate, mix gently until the crystals have completely dissolved. Dilute the EIA Diluent Concentrate 10-fold with reagent grade water to produce a 1x solution. Store for up to 30 days at 2-8 °C. Human Antithrombin III Standard: Reconstitute the Human Antithrombin III Standard (9.6 g) with 2.4 mL of EIA Diluent to generate a 4 g/mL standard stock solution. Allow the vial to sit for 10 minutes with 4 gentle agitation prior to making dilutions. Prepare duplicate or triplicate standard points by serially diluting from the standard stock solution (4 g/mL) 2-fold with equal volume of EIA Diluent to produce 2, 1, 0.5, 0.25, 0.125, and 0.063 g/mL solutions. EIA Diluent serves as the zero standard (0 g/mL). Any remaining stock solution should be stored at -20 °C and used within 30 days. Avoid repeated freeze-thaw cycles. Standard Point Dilution [ATIII] (μg/mL) P1 1 part Standard (4 μg/mL) 4.0 P2 1 part P1 + 1 part EIA Diluent 2.0 P3 1 part P2 + 1 part EIA Diluent 1.0 P4 1 part P3 + 1 part EIA Diluent 0.5 P5 1 part P4 + 1 part EIA Diluent 0.25 P6 1 part P5 + 1 part EIA Diluent 0.125 P7 1 part P6 + 1 part EIA Diluent 0.063 P8 EIA Diluent 0.0 Biotinylated Human Antithrombin III Protein (6x): Reconstitute the Biotinylated Human Antithrombin III Protein with 4 mL of EIA Diluent to produce a stock solution. Allow the vial to sit for 10 minutes with gentle agitation prior to dilution. From the stock solution, dilute 6-fold with EIA Diluent to produce a 1x working solution. Any remaining stock solution should be stored at -20 °C and used within 30 days. Avoid repeated freeze-thaw cycles. 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 to produce a 1x solution. SP Conjugate (100x): Spin down the SP Conjugate briefly and dilute the desired amount of the conjugate 100-fold with EIA Diluent to produce a 1x solution. The undiluted conjugate should be stored at -20 °C.

    样品收集
    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. A 300-fold sample dilution is suggested into EIA Diluent, however, user should determine optimal dilution factor depending on application needs. The undiluted samples can be stored at -20 °C or below for up to 3 months. Avoid repeated freeze-thaw cycles (EDTA or Heparin can also be used as an anticoagulant). 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. A 300-fold sample dilution is suggested into EIA Diluent, however, user should determine optimal dilution factor depending on application needs. The undiluted samples can be stored at -20 °C or below for up to 3 months. Avoid repeated freeze-thaw cycles.
    实验流程

    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 25 l of Human Antithrombin III Standard or sample to each well, and immediately add 25 l of Biotinylated Human ATIII Protein to each 5 well (on top of the standard or sample). Gently tap plate to ensure thorough mixing. 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 SP 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 12 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 low concentration points after stopping the reaction for about 10 minutes, which will reduce the readings.

    结果分析
    • 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.
    实验精密度
    Intra-assay and inter-assay coefficients of variation were 5.1 % and 7.4 % respectively.

    背景
    The serine protease inhibitor antithrombin III (ATIII, serpin C1), the most important natural inhibitor of thrombin activity, has been shown to exert marked anti-inflammatory properties (1). ATIII levels are positively correlated with plasma total cholesterol levels, plasma low-density lipoprotein cholesterol levels, plasma triglycerides, and D-dimer levels (2).
