Trans-signaling enables a wider range of cell types to respond to IL-6,as the expression of gp130is ubiquitous,while that of IL-6R is predominantly restricted to hepatocytes,monocytes,and resting lymphocytes(1-3).Soluble splice forms of gp130 block trans-signaling from IL-6/IL-6R but not from other cytokines that use gp130as a co-receptor(3,41).IL-6,along with TNF-αand IL-1,drives the acute inflammatory response,is almost solely responsible for fever and the acute phase response in the liver,and is important in the transition from acute inflammation to either acquired immunity,or chronic inflammatory disease(1-4).It contributes to chronic inflammation in conditions such as obesity,insulin resistance,inflammatory bowel disease,inflammatory arthritis and sepsis when dysregulated,often involving IL-6trans-signaling(1,2).It also plays an important role in the differentiation of naive T cells to Th17inflammatory cells in the presence of TGF-β.IL-6modulates bone resorption and is a major effector of inflammatory joint destruction in rheumatoid arthritis through its promotion of Th17T cell activity(1).It contributes to atherosclerotic plaque development and destabilization(2). However,IL-6can also have anti-inflammatory effects,such as in skeletal muscle where it is secreted in response to exercise(2).It promotes hematopoiesis by being a growth factor for hematopoietic stem cells,induces B cell maturation to plasma cells and perpetuates multiple myeloma(1,42).IL-6also promotes,but probably does not initiate,other types of inflammation-associated carcinogenesis,such as colitis-associated cancer(1).II.OVERVIEWA.PRINCIPLE OF THE ASSAYThis assay employs the quantitative sandwich enzyme immunoassay technique.A monoclonal antibody specific for IL-6has been pre-coated onto a microplate.Standards and samples are pipetted into the wells and any IL-6present is bound by the immobilized antibody.After washing away any unbound substances,an enzyme-linked polyclonal antibody specific for IL-6is added to the wells.Following a wash to remove any unbound antibody-enzyme reagent,a substrate solution is added to the wells and color develops in proportion to the amount of IL-6bound in the initial step.The color development is stopped and the intensity of the color is measured.B.LIMITATIONS OF THE PROCEDURE♦FOR RESEARCH USE ONLY.NOT FOR USE IN DIAGNOSTIC PROCEDURES.♦This kit is suitable for cell culture supernate,serum and plasma.♦The kit should not be used beyond the expiration date on the kit label.♦Do not mix or substitute reagents with those from other lots or sources.♦If samples generate values higher than the highest standard,dilute the samples with Diluent and repeat the assay.♦Any variation in operator,pipetting technique,washing technique,incubation time or temperature,and kit age can cause variation in binding.III.ADVANTAGESA.PRECISIONIntra-assay Precision(Precision within an assay)Three samples were tested twenty times on one plate to assess intra-assay precision.

Samples may require dilution with Calibrator Diluent1×.Serum-Use a serum separator tube(SST)and allow samples to clot for30minutes at room temperature before centrifugation for15minutes at1000x g.Remove serum and assay immediately or aliquot and store samples at≤-20°C.Avoid repeated freeze-thaw cycles.Plasma-Collect plasma using EDTA,heparin,or citrate as an anticoagulant. Centrifuge for15minutes at1000x g within30minutes of collection.Assay immediately or aliquot and store samples at≤-20°C.Avoid repeated freeze-thaw cycles.B.SAMPLE PREPARATIONSerum samples require a5-fold dilution.A suggested5-fold dilution is40μL of sample +160μL of Diluent(1×).Plasma samples require a2-fold dilution.A suggested2-fold dilution is100μL of sample+100μL of Diluent(1×).C.REAGENT PREPARATIONNote:Bring all reagents to room temperature before use.Wash Buffer-If crystals have formed in the concentrate,warm to room temperature and mix gently until the crystals have completely dissolved.Dilute20mL of Wash Buffer Concentrate(25×)into deionized or distilled water to prepare500mL of Wash Buffer. Diluent1×-Add20mL of Calibrator Diluent Concentrate5×into80mL of deionized or distilled water to prepare100mL of Diluent1×.IL-6Standard-Refer to the vial label for reconstitution volume*.This reconstitution produces a stock solution of300pg/mL.Allow the standard to sit for a minimum of15 minutes with gentle agitation prior to making dilutions.*if you have any question,please seek help from our Technical Support.Pipette667μL of Diluent1×into the100pg/mL tube.Pipette500μL of Diluent 1×into each remaining e the stock solution to produce a dilution series (below).Mix each tube thoroughly before the next transfer.The undiluted standard serves as the high standard(300pg/mL).The Diluent1×serves as the zero standard(0 pg/mL).D.TECHNICAL HINTS●When mixing or reconstituting protein solutions,always avoid foaming.●To avoid cross-contamination,change pipette tips between additions of eachstandard level,between sample additions,and between reagent additions.Also, use separate reservoirs for each reagent.●It is recommended that the samples be pipetted within15minutes.●To ensure accurate results,proper adhesion of plate sealers during incubationsteps is necessary.●TMB Substrate should remain colorless until added to the plate.Keep SubstrateSolution protected from light.Substrate Solution should change from colorless to gradations of blue.●Stop Solution should be added to the plate in the same order as the SubstrateSolution.The color developed in the wells will turn from blue to yellow upon addition of the Stop Solution.Wells that are green in color indicate that the Stop Solutionhas not mixed thoroughly with the Substrate Solution.VII.ASSAY PROCEDURENote:Bring all reagents and samples to room temperature before use.It is recommended that all samples and standards be assayed in duplicate.1.Prepare all reagents and working standards as directed in the previous sections.2.Remove excess microplate strips from the plate frame,return them to the foil pouchcontaining the desiccant pack,and reseal.3.Add100μL of Standard,sample,or control per well.Cover with the adhesive stripprovided.Incubate for2hours at room temperature.A plate layout is provided for a record of standards and samples assayed.4.Aspirate each well and wash,repeating the process three times for a total of fourwashes.Wash by filling each well with Wash Buffer(400μL)using a squirt bottle, manifold dispenser,or plete removal of liquid at each step is essential to good performance.After the last wash,remove any remaining Wash Buffer by aspirating or decanting.Invert the plate and blot it against clean paper towels.5.Add200μL of human IL-6Conjugate to each well.Cover with a new adhesive strip.Incubate for2hours at room temperature.6.Repeat the aspiration/wash as in step4.7.Add200μL of TMB Substrate to each well.Incubate for20minutes at roomtemperature.Protect from light.8.Add50μL of Stop Solution to each well.The color in the wells should change fromblue to yellow.If the color in the wells is green or if the color change does not appear uniform,gently tap the plate to ensure thorough mixing.9.Determine the optical density of each well within10minutes,using a microplatereader set to450nm.If wavelength correction is available,set to540nm or570nm.If wavelength correction is not available,subtract readings at540nm or570nm from the readings at450nm.This subtraction will correct for optical imperfections in the plate.Readings made directly at450nm without correction may be higher and less accurate.10.CALCULATION OF RESULTS：Average the duplicate readings for each standard,control,and sample and subtract the average zero standard optical density.Createa standard curve by reducing the data using computer software capable ofgenerating a four parameter logistic(4-PL)curve-fit.As an alternative,construct a standard curve by plotting the mean absorbance for each standard on the y-axis against the concentration on the x-axis and draw a best fit curve through the points on the graph.The data may be linearized by plotting the log of the IL-6 concentrations versus the log of the O.D.and the best fit line can be determined by regression analysis.This procedure will produce an adequate but less precise fit of the data.If samples have been diluted,the concentration read from the standard curve must be multiplied by the dilution factor.VIII.REFERENCES1.Naugler,W.E.and M.Karin(2008)Trends Mol.Med.14:109.2.Schuett,H.et al.(2009)Thromb.Haemost.102:215.3.Jones,S.A.(2005)J.Immunol.175:3468.4.Hodge,D.R.et
