羊肿瘤坏死因子α（TNF-α）试剂盒使用说明书本试剂盒仅供研究使用。检测范围：96T50ng/L-1300ng/L使用目的：本试剂盒用于测定羊血清、血浆及相关液体样本中肿瘤坏死因子α（TNF-α）含量。试剂盒组成130倍浓缩洗涤液20ml×1瓶7终止液6ml×1瓶2酶标试剂6ml×1瓶8标准品（2400ng/L）0.5ml×1瓶3酶标包被板12孔×8条9标准品稀释液1.5ml×1瓶4样品稀释液6ml×1瓶10说明书1份5显色剂A液6ml×1瓶11封板膜2张6显色剂B液6ml×1/瓶12密封袋1个标本要求1．标本采集后尽早进行提取，提取按相关文献进行，提取后应尽快进行实验。若不能马上进行试验，可将标本放于-20℃保存，但应避免反复冻融2．不能检测含NaN3的样品，因NaN3YZ辣根过氧化物酶的（HRP）活性。羊肿瘤坏死因子α试剂盒操作步骤1.标准品的稀释：本试剂盒提供原倍标准品一支，用户可按照下列图表在小试管中进行稀释。1200ng/L5号标准品150μl的原倍标准品加入150μl标准品稀释液600ng/L4号标准品150μl的5号标准品加入150μl标准品稀释液300ng/L3号标准品150μl的4号标准品加入150μl标准品稀释液150ng/L2号标准品150μl的3号标准品加入150μl标准品稀释液75ng/L1号标准品150μl的2号标准品加入150μl标准品稀释液2.加样：分别设空白孔（空白对照孔不加样品及酶标试剂，其余各步操作相同）、标准孔、待测样品孔。在酶标包被板上标准品准确加样50μl，待测样品孔中先加样品稀释液40μl，然后再加待测样品10μl（样品Z终稀释度为5倍）。加样将样品加于酶标板孔底部，尽量不触及孔壁，轻轻晃动混匀。3.温育：用封板膜封板后置37℃温育30分钟。4.配液：将30倍浓缩洗涤液用蒸馏水20倍稀释后备用5.洗涤：小心揭掉封板膜，弃去液体，甩干，每孔加满洗涤液，静置30秒后弃去，如此重复5次，拍干。6.加酶：每孔加入酶标试剂50μl，空白孔除外。7.温育：操作同3。8.洗涤：操作同5。9.显色：每孔先加入显色剂A50μl，再加入显色剂B50μl，轻轻震荡混匀，37℃避光显色15分钟.10.终止：每孔加终止液50μl，终止反应（此时蓝色立转黄色）。11.测定：以空白空调零，450nm波长依序测量各孔的吸光度（OD值）。测定应在加终止液后15分钟以内进行。羊肿瘤坏死因子α试剂盒注意事项1．试剂盒从冷藏环境中取出应在室温平衡15-30分钟后方可使用，酶标包被板开封后如未用完，板条应装入密封袋中保存。2．浓洗涤液可能会有结晶析出，稀释时可在水浴中加温助溶，洗涤时不影响结果。3．各步加样均应使用加样器，并经常校对其准确性，以避免试验误差。一次加样时间**控制在5分钟内，如标本数量多，推荐使用排枪加样。4．请每次测定的同时做标准曲线，**做复孔。如标本中待测物质含量过高（样本OD值大于标准品孔**孔的OD值），请先用样品稀释液稀释一定倍数（n倍）后再测定，计算时请Z后乘以总稀释倍数（×n×5）。5．封板膜只限一次性使用，以避免交叉污染。6．底物请避光保存。7．严格按照说明书的操作进行，试验结果判定必须以酶标仪读数为准.8．所有样品，洗涤液和各种废弃物都应按传染物处理。9．本试剂不同批号组分不得混用。10.如与英文说明书有异，以英文说明书为准。保存条件及有效期1．试剂盒保存：；2-8℃。2．有效期：6个月MouseTumornecrosisfactorαFORRESEARCHUSEONLYAssayrange：25ng/L-800ng/L96determinationsPurposeThiskitallowsforthedeterminationofTNF-αconcentrationsinMouseserum,cellculturesupernatesandotherbiologicalfluidsPrincipleoftheassayThekitassayMouseTNF-αlevelinthesample，usePurifiedMouseTNF-αantibodytocoatmicrotiterplatewells,makesolid-phaseantibody,thenaddTNF-αtowells,CombinedantibodywhichWithHRPlabeledgoatanti-mousebecomeantibody-antigen-enzyme-antibodycomplex,afterwashingCompletely,AddTMBsubstratesolution,TMBsubstratebecomesbluecolorAtHRPenzyme-catalyzed,reactionisterminatedbytheadditionofasulphuricacidsolutionandthecolorchangeismeasuredspectrophotometricallyatawavelengthof450nm.TheconcentrationofTNF-αinthesamplesisthendeterminedbycomparingtheO.D.ofthesamplestothestandardcurve.Materialsprovidedwiththekit1washsolution20ml×1bottle7StoppSolution6ml×1bottle2HRP-Conjugatereagent6ml×1bottle8Standard（1600ng/L）0.5ml×1bottle3Microelisastripplate12well×8strips9Standarddiluent1.5ml×1bottle4Samplediluent6ml×1bottle10Instruction15ChromogenSolutionA6ml×1bottle11Closureplatemembrane26ChromogenSolutionB6ml×1bottle12Sealedbags1Specimenrequirements1.extractassoonaspossibleafterSpecimencollection,andaccordingtotherelevantliterature,and首ldbeexperimentassoonaspossibleaftertheextraction.Ifitcan’t,specimencanbekeptin-20℃topreserve,Avoidrepeatedfreeze-thawcycles.2.Can’tdetectthesamplewhichcontainNaN3,becauseNaN3inhibitsHRPactive.Assayprocedure1.Diluteandaddsample:DiluteOriginaldensityStandardasfollowtable:800ng/L5Standard150μlOriginaldensityStandard+150μlStandarddiluent400ng/L4Standard150μl5Standard+150μlStandarddiluent200ng/L3Standard150μl4Standard+150μlStandarddiluent100ng/L2Standard150μl3Standard+150μlStandarddiluent50ng/L1Standard150μl2Standard+150μlStandarddiluent2.addsample：Setblankwellsseparately（blankcomparisonwellsdon’taddsampleandHRP-Conjugatereagent,othereachstepoperationissame）.testingsamplewell.addSampledilution40μltotestingsamplewell,thenaddtestingsample10μl（samplefinaldilutionis5-fold）,addsampletowells,don’ttouchthewellwallasfaraspossible,andGentlymix.3.Incubate:AfterclosingplatewithClosureplatemembrane,incubatefor30minat37℃.4.Configurateliquid:30-foldwashsolutiondiluted30-fold（or20-fold）withdistilledwaterandreserve.5.washing：UncoverClosureplatemembrane,discardLiquid,drybyswing,addwashingbuffertoeverywell,stillfor30sthendrain,repeat5times,drybypat.6.addenzyme：AddHRP-Conjugatereagent50μltoeachwell,exceptblankwell.7.incubate：Operationwith3.8.washing：Operationwith5.9.color：AddChromogenSolutionA50ulandChromogenSolutionBtoeachwell,evadethelightpreservationfor15minat37℃10.Stopthereaction：AddStopSolution50μltoeachwell,Stopthereaction（thebluecolorchangetoyellowcolor）.11.assay：takeblankwellaszero,Readabsorbanceat450nmafterAddingStopSolutionandwithin15min.StepsdescriptionStandard,SamplediluentAddStandard,Samplediluent,incubatefor30minat37℃.Wash5time,AddHRP-Conjugatereagent,incubatefor30minat37℃.Wash5time,AddChromogenSolutionAandB,incubatefor10minat37℃.AddStoppSolutionReadabsorbanceat450nmwithin15mincalculateCalculateTakethestandarddensityasthehorizontal,theODvalueforthevertical,drawthestandardcurveongraphpaper,FindoutthecorrespondingdensityaccordingtothesampleODvaluebytheSamplecurve,multipliedbythedilutionmultiple,orcalculatethestraightlineregressionequationofthestandardcurvewiththestandarddensityandtheODvalue,withthesampleODvalueintheequation,calculatethesampledensity,multipliedbythedilutionfactor,theresultisthesampleactualdensity.Importantnotes1.Thekittakesoutfromtherefrigerationenvironment首ldbebalanced15-30minutesintheroom
