猴风疹病毒抗体IgM(RV-IgM)酶联免疫分析(ELISA)试剂盒利用说明书本试剂仅供研究利用目的:本试剂盒用于检测猴血清,血浆中风疹病毒抗体IgM(RV-IgM)水平,感染人的血液学诊断。实验原理:本试剂盒采用双抗原夹心酶联免疫法(ELISA)测定标本中猴风疹病毒抗体IgM(RV-IgM)。用纯化的抗原包被微孔板,制成固相抗原,可与样品中风疹病毒抗体IgM(RV-IgM)相结合,经洗涤除去未结合的抗体和其他成份后再与HRP标记的抗原结合,形成抗原T亢体-酶标抗原复合物,通过完全洗涤后加底物TMB显色。TMB住HRP酶的催化下转化成蓝色,并在酸的作用下转化成最终的黄色。用酶标仪在450nm波长下测定吸光度(0D值),与CUTOFF值相较较,从而判定标本中猴风疹病毒抗体IgKRV-IgM)的存在与否。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(48)2片(96)密封袋1个1个酶标包被板1X481X962-8C保存阴性对照XI瓶XI瓶2-8C保存阳性对照XI瓶XI瓶2-8C保存酶标试剂3mlXl瓶6mlXl瓶2-8C保存样品稀释液3mlXl瓶6mlX1瓶2-8保存显色剂A液3mlX1瓶6mlX1瓶2-8C保存显色剂B液3mlXl瓶6mlX1瓶2-8保存终止液3mlX1瓶6mlX1瓶2-8C保存浓缩洗涤液(20mlX20倍)XI瓶(20mlX30倍)XI瓶2-8保存样本处置及要求:1 .血清:室温血液自然凝固10-20分钟,离心20分钟左右(2OOO-3OOO转/分)。认真搜集上清,保留进程中如显现沉淀,应再次离心。2 .血浆:应依照标本的要求选择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(2OOO-3OOO转/分)。认真搜集上清,保留进程中如有沉淀形成,应该再次离心。3 .尿液:用无菌管搜集,离心20分钟左右(2000-3000转/分)。认真搜集上清,保留进程中如有沉淀形成,应再次离心。胸腹水、脑脊液参如实行。4 .细胞培育上清:检测分泌性的成份时,用无菌管搜集。离心20分钟左右(2000-3000转/分)。认真搜集上清。检测细胞内的成份时,用PBS()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)。认真搜集上清。保留进程中如有沉淀形成,应再次离心。5 .组织标本:切割标本后,称取重量。加入必然量的PBS,。用液氮迅速冷冻保留备用。标本融化后仍然维持2-8的温度。加入必然量的PBS(),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)。认真搜集上清。分装后一份待检测,其余冷冻备用。6 .标本搜集后及早进行提取,提取按相关文献进行,提取后应尽快进行实验。假设不能马上进行实验,可将标本放于-20保留,但应幸免反复冻融.7 .不能检测含NaN3的样品,因NaN3抑制辣根过氧化物酶的(HRP)活性。操作步骤:1 .编号:将样品对应微孔按序编号,每板应设阴性对照2孔、阳性对照2孔、空白对照1孔(空白对照孔不加样品及酶标试剂,其余各步操作相同)2 .加样:别离在阴、阳性对照孔中加入阴性对照、阳性对照50诅.然后在待测样品孔先加样品稀释液40山,然后再加待测样品10可。加样将样品加于酶标板孔底部,尽可能不触及孔壁,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(48T的20倍)倍浓缩洗涤液加蒸储水至600ml后备用5 .洗涤:警惕揭掉封板膜,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50m,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A50可,再加入显色剂B50pl,轻轻震荡混匀,37避光显色15分钟10 .终止:每孔加终止液50皿,终止反映(现在蓝色立转黄色)。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分钟之内进行。结果判定:实验有效性:阳性对照孔平均值三阴性对照平均值W临界值(CUTOFF)计算:临界值=阴性对照孔平均值十阴性判定:样品OD值临界值(CUTOFF)者为风疹病毒IgM(RV-IgM)抗体阴性阳性判定:样品OD值N临界值(CUTOFF)者为风疹病毒IgM(RV-IgM)抗体阳性注意事项1 .操作严格依照说明书进行,本试剂不同批号组分不得混用。2 .试剂盒从冷藏环境中掏出应在室温平稳15-30分钟后方可利用,酶标包被板开封后如未用完,板条应装入密封袋中保留。3 .浓洗涤液可能会有结晶析出,稀释时可在水浴中加温助溶,洗涤时不阻碍结果。4 .封板膜只限一次性利用,以幸免交叉污染。5 .底物请避光保留。6 .实验结果判定必需以醯标仪读数为准,利用双波长检测时,参考波长为630nm7 .所有样品,洗涤液和各类废弃物都应按传染物处置。终止液为2M的硫酸,利历时必需注意平安。保留条件及有效期1 .试剂盒保留:2-832 .有效期:6个月RDHumanRV-IgMantibodyFORRESEARCHUSEONLYDrugNamesGenericName:HumanRV-IgMAbELISAKit.PurposeThiskitallowsforthedeterminationofRV-IgMAbconcentrationsinHumanserum,andotherbiologicalfluids.PrincipleoftheassayThekitassayRV-IgMAblevelinthesample,usePurifiedantigentocoatmicrotiterplatewells,makesolid-phaseantigen,thenaddRV-IgMantibodytowells,CombinedWithantigen,afterwashingandremovingnon-combinativeantigenandothercomponents,thenCombinedantigenwhichwithHRPlabeledbecomeantigen-antibody-enzyme-antigencomplex,afterwashingCompletely,AddTMBsubstratesolution,TMBsubstratebecomesbluecolorAtHRPenzyme-catalyzed,reactionisterminatedbytheadditionofasulphuricacidsolutionandthecolorchangeismeasuredspectrophotometricallyatawavelengthof450nm.ComparedwiththeCUTOFFvalue,accordingtothistojudgeRV-IgMAbexistinthesampleornot.MaterialsprovidedwiththekitMaterialsprovidedwiththekit48determinations96determinationsStorageUsermanual11Closureplatemembrane22Sealedbags11Microelisastripplate112-8NegativecontrolX1bottleX1bottle2-8PositivecontrolX1bottleX1bottle2-8HRP-Conjugatereagent3mlx1bottle6mlx1bottle2-8Samplediluent3mlx1bottle6mlx1bottle2-8ChromogenSolutionA3mlx1bottle6mlx1bottle2-8ChromogenSolutionB3mlx1bottle6mlx1bottle2-8StopSolution3mlx1bottle6mlx1bottle2-8washsolution(20mlX20fold)x1bottle(20mlX30fold)xIbottle2-8Specimenrequirements1. serum-coagulationatroomtemperature10-20mins,centrifugation20-minatthespeedof2000-3000removesupernatant,Ifprecipitationappeared,Centrifugalagain.2. plasma-usesuitedEDTAorcitrateplasmaasananticoagulant,mix10-20mins,centrifugation20-minatthespeedof2000-3000removesupernatant,Ifprecipitationappeared,Centrifugalagain.3.
