    实验流程
    This assay employs a quantitative sandwich enzyme immunoassay technique that measures CRP in 3.5 hours. A polyclonal antibody specific for rat CRP has been pre-coated onto a microplate. CRP in standards and samples is sandwiched by the immobilized antibody and biotinylated polyclonal antibody specific for CRP, which is recognized by a streptavidin-peroxidase conjugate. All unbound material is then 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. If crystals have formed in the concentrate, mix gently until the crystals have completely dissolved. EIA Diluent Concentrate (10x): Dilute the EIA Diluent 1:10 with reagent grade water. Store for up to 1 month at 2-8°C. CRP Standard: Reconstitute the 100 ng of rat CRP Standard with 2.0 ml of EIA Diluent to generate a 50 ng/ml of solution. Allow the standard to sit for 10 minutes with gentle agitation prior to making dilutions. Prepare triplicate standard points by serially diluting the Standard solution (50 ng/ml) 1:2 with equal volume of EIA Diluent to produce 25, 12.5, 2 6.25, 3.13, 1.562 and 0.78 ng/ml. EIA Diluent serves as the zero standard (0 ng/ml). Any remaining solution should be frozen at -20°C.

Any remaining solution should be frozen at -20°C. Wash Buffer Concentrate (20x): Dilute the Wash Buffer Concentrate 1:20 with reagent grade water. SP Conjugate (100x): Spin down the SP Conjugate briefly and dilute the desired amount of the conjugate 1:100 with EIA Diluent. Any remaining solution should be frozen at -20°C.

    样品收集
    Urine: Collect urine using sample pot. Centrifuge samples at 600 x g for 10 minutes and assay. Dilute samples 1:4 into EIA Diluent. Store samples at -20°C or below for up to 3 months. Avoid repeated freeze-thaw cycles. Cell Culture Supernatants: Centrifuge cell culture media at 2000 x g for 10 minutes to remove debris. Collect supernatants and assay. The samples can be stored at -20°C or below. Avoid repeated freeze-thaw cycles.
    实验流程

    Prepare all reagents, working standards and samples as instructed. Bring all reagents to room temperature before use. The assay is performed at room temperature (20 - 30 °C). Remove excess microplate strips from the plate frame and return them immediately to the foil pouch with desiccant inside. Reseal the pouch securely to minimize exposure to water vapor and store in a vacuum desiccator. Add 50 µL of Standard or sample per well. Cover wells with a sealing tape and incubate for two hours. Start the timer after the last sample addition. Wash five times with 200 µL of Wash Buffer. Invert the plate and decant the contents, and hit it 4-5 times on absorbent paper towel to complete remove liquid at each step. Add 50 µL of Biotinylated CRP Antibody to each well and incubate for 1 hour. Wash five times with 200 µL of Wash Buffer as above. Add 50 µL of Streptavidin-Peroxidase Conjugate per well and incubate for 30 minutes. Turn on the microplate reader and set up the program in advance. Wash five times with 200 µL of Wash Buffer as above. Add 50 µL of Chromogen Substrate per well and incubate for about 10 minutes or till the optimal color density develops. Gently tap the plate to ensure thorough mixing and break the bubbles in the well with pipette tip. Add 50 µL of Stop Solution to each well. The color will change from blue to yellow. Read the absorbance on a microplate reader at a wavelength of 450 nm immediately. Please note that some unstable black particles may be generated at high optical densities to reduce the readings after stopping the reaction for about 10 minutes.

    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 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. Standard Curve The curve is provided for illustration only. A standard curve should be generated each time the assay is performed.

    背景
    C-Reactive Protein (CRP) is a liver protein composed of five identical nonglycosylated subunits, with a total molecular weight of 105 kDa. CRP has a variety of powerful effects related to immunology, inflammation, and coagulation. As a marker of low-level inflammation, CRP appears to predict future cardiovascular disease events among apparently healthy individuals. High plasma concentration of CRP was associated with increased risk of stroke, myocardial infarction, and peripheral vascular disease. CRP has also been associated with increased risks of fatal coronary events among high-risk male smokers and incident coronary disease among the elderly. Studies have established the prognostic usefulness of CRP in the setting of angina. Originally used as a marker of acute inflammation, CRP has become a leading candidate as the measure of choice for estimating the inflammatory component of cardiovascular disease risk.
