人白介素2受体(IL-2R)酶联免疫分析(ELISA)试剂盒使用说明书本试剂仅供研究使用目的:本试剂盒用于测定人血清、血浆、组织等样本中白介素2受体(IL-2R)的含量。实验原理:本试剂盒应用双抗体夹心法测定标本中人白介素2受体(IL-2R)水平。用纯化的人白介素2受体(IL-2R)抗体包被微孔板,制成固相抗体,往包被单抗的微孔中依次加入人白介素2受体(IL-2R),再与HRP标记的人白介素2受体(IL-2R)抗体结合,形成抗体-抗原-酶标抗体复合物,经过彻底洗涤后加底物TMB显色。TMB在HRP酶的催化下转化成蓝色,并在酸的作用下转化成Z终的黄色。颜色的深浅和样品中的人白介素2受体(IL-2R)呈正相关。用酶标仪在450nm波长下测定吸光度(OD值),通过标准曲线计算样品中人白介素2受体(IL-2R)含量。试剂盒组成:试剂盒组成48孔配置96孔配置保存说明书1份1份封板膜2片2片密封袋1个1个酶标包被板1×481×962-8℃保存标准品0.3ml×6管0.3ml×6管2-8℃保存酶标试剂5ml×1瓶10ml×1瓶2-8℃保存样品稀释液3ml×1瓶6ml×1瓶2-8℃保存显色剂A液3ml×1瓶6ml×1瓶2-8℃保存显色剂B液3ml×1瓶6ml×1瓶2-8℃保存终止液3ml×1瓶6ml×1瓶2-8℃保存20×浓缩洗涤液15ml×1瓶25ml×1瓶2-8℃保存注:标准品浓度依次为:800、400、200、100、50、0ng/L.样本处理及要求:1.血清:室温血液自然凝固10-20分钟,离心20分钟左右(2000-3000转/分)。仔细收集上清,保存过程中如出现沉淀,应再次离心。2.血浆:应根据标本的要求选择EDTA或柠檬酸钠作为抗凝剂,混合10-20分钟后,离心20分钟左右(2000-3000转/分)。仔细收集上清,保存过程中如有沉淀形成,应该再次离心。3.尿液:用无菌管收集,离心20分钟左右(2000-3000转/分)。仔细收集上清,保存过程中如有沉淀形成,应再次离心。胸腹水、脑脊液参照实行。4.细胞培养上清:检测分泌性的成份时,用无菌管收集。离心20分钟左右(2000-3000转/分)。仔细收集上清。检测细胞内的成份时,用PBS(PH7.2-7.4)稀释细胞悬液,细胞浓度达到100万/ml左右。通过反复冻融,以使细胞破坏并放出细胞内成份。离心20分钟左右(2000-3000转/分)。仔细收集上清。保存过程中如有沉淀形成,应再次离心。5.组织标本:切割标本后,称取重量。加入一定量的PBS,PH7.4。用液氮迅速冷冻保存备用。标本融化后仍然保持2-8℃的温度。加入一定量的PBS(PH7.4),用手工或匀浆器将标本匀浆充分。离心20分钟左右(2000-3000转/分)。仔细收集上清。分装后一份待检测,其余冷冻备用。6.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.7.不能检测含NaN3的样品,因NaN3YZ辣根过氧化物酶的(HRP)活性。操作步骤标准品的加样:设置标准品孔和样本孔,标准品孔各加不同浓度的标准品50μL;。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)、待测样品孔。在酶标包被板上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。温育:用封板膜封板后置37℃温育30分钟。配液:将30(48T的20倍)倍浓缩洗涤液用蒸馏水30(48T的20倍)倍稀释后备用。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。加酶:每孔加入酶标试剂50μl,空白孔除外。温育:操作同3。洗涤:操作同5。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.终止:每孔加终止液50μl,终止反应(此时蓝色立转黄色)。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。注意事项: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。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。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。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)。封板膜只限一次性使用,以避免交叉污染。底物请避光保存。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.所有样品,洗涤液和各种废弃物都应按传染物处理。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。计算:以标准物的浓度为横坐标,OD值为纵坐标,在坐标纸上绘出标准曲线,根据样品的OD值由标准曲线查出相应的浓度;再乘以稀释倍数;或用标准物的浓度与OD值计算出标准曲线的直线回归方程式,将样品的OD值代入方程式,计算出样品浓度,再乘以稀释倍数,即为样品的实际浓度。(此图仅供参考)试剂盒性能:1.样品线性回归与预期浓度相关系数R值为0.95以上。2.批内与批见应分别小于9%和11%检测范围:25ng/L-800ng/L保存条件及有效期:1.试剂盒保存:;2-8℃。2.有效期:6个月HumanInterleukin-2receptorFORRESEARCHUSEONLYDrugNamesGenericName:HumanInterleukin-2receptor(IL-2R)ELISAKit.PurposeThiskitallowsforthedeterminationofIL-2RconcentrationsinHumanserum,bloodplasma,andotherbiologicalfluids.PrincipleoftheassayThekitassayHumanIL-2Rlevelinthesample,usePurifiedHumanIL-2Rantibodytocoatmicrotiterplatewells,makesolid-phaseantibody,thenaddIL-2Rtowells,CombinedIL-2RantibodywhichWithHRPlabeled,becomeantibody-antigen-enzyme-antibodycomplex,afterwashingCompletely,AddTMBsubstratesolution,TMBsubstratebecomesbluecolorAtHRPenzyme-catalyzed,reactionisterminatedbytheadditionofasulphuricacidsolutionandthecolorchangeismeasuredspectrophotometricallyatawavelengthof450nm.TheconcentrationofIL-2RinthesamplesisthendeterminedbycomparingtheO.D.ofthesamplestothestandardcurve.MaterialsprovidedwiththekitMaterialsprovidedwiththekit48determinations96determinationsStorageUsermanual11Closureplatemembrane22Sealedbags11Microelisastripplate112-8℃Standard0.3ml×6bottle0.3ml×6bottle2-8℃HRP-Conjugatereagent5ml×1bottle10ml×1bottle2-8℃Samplediluent3ml×1bottle6ml×1bottle2-8℃ChromogenSolutionA3ml×1bottle6ml×1bottle2-8℃ChromogenSolutionB3ml×1bottle6ml×1bottle2-8℃StopSolution3ml×1bottle6ml×1bottle2-8℃20×Washsolution15ml×1bottle25ml×1bottle2-8℃Note:Standardconcentrationwasfollowedby:800、400、200、100、50、0ng/L.Specimenrequirementsserum-coagulationatroomtemperature10-20mins,centrifugation20-minatthespeedof2000-3000r.p.m.removesupernatant,Ifprecipitationappeared,Centrifugalagain.plasma-usesuitedEDTAorcitrateplasmaasananticoagulant,mix10-20mins,centrifugation20-minatthespeedof2000-3000r.p.m.removesupernatant,Ifprecipitationappeared,Centrifugalagain.Urine-collectsueasterilecontainer,centrifugation20-minatthespeedof2000-3000r.p.m.removesupernatant,Ifprecipitationappeared,Centrifugalagain.TheOperationofHydrothoraxandcerebrospinalfluidReferencetoit.cellculturesupernatant-detectsecretorycomponents,collectsueasterilecontainer,centrifugation20-minatthespeedof2000-3000r.p.m.removesupernatant,detectthecompositionofcells,DilutcellsuspensionwithPBS(PH7.2-7.4),Cellconcentrationreached1million/ml,repeatedfreeze-thawcycles,damagecellsandreleaseofintracellularcomponents,centrifugation20-minatthespeedof2000-3000r.p.m.removesupernatant,Ifprecipitationappeared,Centrifugalagain.Tissuesamples-Aftercuttingsamples,checktheweight,addPBS(PH7.2-7.4),Rapidlyfrozenwithliquidnitrogen,maintainsamplesat2-8℃aftermelting,addPBS(PH7.4),HomogenizedbyhandorGrinders,centrifugation20-minatthespeedof2000-3000r.p.m.removesupernatant.extractassoonaspossibleafterSpecimencollection,andaccordingtotherelevantliterature,and首ldbeexperimentassoonaspossibleaftertheextraction.Ifitcan’t,specimencan
