    Fonction
    The OmniKine? Human IL-6R ELISA Kit contains the components necessary for quantitative determination of natural or recombinant Human IL-6R concentrations within any experimental sample including cell lysates, serum and plasma. This particular immunoassay utilizes the quantitative technique of a "Sandwich" Enzyme-Linked Immunosorbent Assay (ELISA) where the target protein (antigen) is bound in a "sandwich" format by the primary capture antibodies coated to each well-bottom and the secondary detection antibodies added subsequently by the investigator. The capture antibodies coated to the bottom of each well are specific for a particular epitope on Human IL-6R while the user-added detection antibodies bind to epitopes on the captured target protein. Amid each step of the procedure, a series of wash steps must be performed to ensure the elimination of non- specific binding between proteins to other proteins or to the solid phase. After incubation and "sandwiching" of the target antigen, a peroxidase enzyme is conjugated to the constant heavy chain of the secondary antibody (either covalently or via Avidin/Streptavidin-Biotin interactions), allowing for a colorimetric reaction to ensue upon substrate addition. When the substrate TMB (3, 3', 5, 5'-Tetramethylbenzidine) is added, the reaction catalyzed by peroxidase yields a blue color that is representative of the antigen concentration. Upon sufficient color development, the reaction can be terminated through addition of Stop Solution (2 N Sulfuric Acid) where the color of the solution will turn yellow. The absorbance of each well can then be read by a spectrophotometer, allowing for generation of a standard curve and subsequent determination of protein concentration.

    Préparation de l'échantillon

    If samples are to be used within 24 hours, aliquot and store at 4 °C. If samples are to be used over a long period of time, aliquot and store between -20 °C and -80 °C, depending on the duration of storage.
    Note: Samples containing a visible precipitate or pellet must be clarified prior to use in the assay.
    Caution: Avoid repeated freeze/thaw cycles to prevent loss of biological activity of proteins in experimental samples.

    • Cell Lysate and Supernatants:
      Remove large cell components via centrifugation and perform the assay. Cell lysates and supernatants require a dilution using Assay Diluent. A serial dilution may be performed to determine a suitable dilution factor for the sample. For future use of the sample, follow the sample storage guidelines stated above.
    • Serum:
      Allow samples to clot in a serum separator tube (SST) for 30 minutes. After sufficient clotting, centrifuge at 1000 x g for 15 minutes and remove serum from SST in preparation for the assay. Serum samples require at least a 1:50 dilution using Assay Diluent. For future use of the sample, follow the storage guidelines above.
    • Plasma:
      Use heparin, citrate or EDTA as an anticoagulant to gather plasma from original biological sample. After collection of the plasma, centrifuge for 15 minutes at 1000 x g. This step must be performed within 30 minutes of plasma collection. Plasma samples require at least a 1:50 dilution using Assay Diluent. Afterwards, perform the assay or for future use of the sample, follow the storage guidelines stated above.

    Procédure de l'essai

    Note: If possible, all incubation steps should be performed on an orbital shaker to equilibrate solutions when added to the microplate wells. Also, all provided solutions should be at ambient temperature prior to use.
    Note: Avoid adding solutions into wells at an angle, always keep pipette tip perpendicular to plate bottom.

      2. Reconstitute the Protein Standard in 100 µL of ddH₂O for a concentration of 340 ng/ml.
      3. Dilute the 50 mL of 10x Wash Buffer in 450 mL of ddH2O for 500 mL of 1x Wash Buffer.
    Addition of Known Standard and Unknown Sample to Immunoassay:
      The OmniKine™ Human CD163 ELISA Kit allows for the detection and quantification of endogenous levels of natural and/or recombinant Human CD163 proteins

    Calcul des résultats

    Generation of Standard Curve and Interpretation of Data
    1. Average the duplicate or triplicate readings for each standard, control and sample and subtract the average zero standard optical density.
    2. Generate a standard curve by using Microsoft Excel or other computer software capable of establishing a 4- Parameter Logistic (4-PL) curve fit. If using Excel or an alternative graphing tool, plot the average optical density values in absorbance units (y-axis) against the known standard concentrations in pg/ml (x-axis). Note: Only use the values in which a noticeable gradient can be established. Afterwards, generate a best fit curve or trend-line through the plotted points via regression analysis.

    Sujet
    IL-6R1 is part of the receptor for interleukin 6. This receptor binds to IL6 with low affinity, but does not transduce a signal. Signal activation necessitates an association with IL6ST. While activation may lead to the regulation of the immune response, acute-phase reactions and hematopoiesis, low concentration of a soluble form of IL6 receptor acts as an agonist of IL6 activity. IL-6R1 is a hexamer of two molecules each of IL6, IL6R and IL6ST. Isoform 2 is expressed in peripheral blood mononuclear cells and weakly found in urine and serum. The two fibronectin type-III-like domains, contained in the N-terminal part, form together a cytokine-binding domain. Studies have shown that the WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding. A short soluble form may also be released from the membrane by proteolysis. This gene encodes a subunit of the interleukin 6 (IL6) receptor complex. Interleukin 6 is a potent pleiotropic cytokine that regulates cell growth and differentiation and plays an important role in the immune response. The IL6 receptor is a protein complex consisting of this protein and interleukin 6 signal transducer (IL6ST/GP130/IL6-beta), a receptor subunit also shared by many other cytokines. Dysregulated production of IL6 and this receptor are implicated in the pathogenesis of many diseases, such as multiple myeloma, autoimmune diseases and prostate cancer. Alternatively spliced transcript variants encoding distinct isoforms have been reported. A pseudogene of this gene is found on chromosome 9. Source: Entrez Gene, Swiss-Prot
