人磷脂酰肌醇抗體IgM(PIAb-IgM)酶聯(lián)免疫分析(ELISA)

試劑盒使用說明書本試劑僅供研究使用目的：本試劑盒用于測定人血清，血漿及相關(guān)液體樣本中磷脂酰肌醇抗體IgM(PIAb-IgM)的含量。實驗原理：本試劑盒應(yīng)用雙抗原夾心法測定標(biāo)本中人磷脂酰肌醇抗體IgM(PIAb-IgM)水平。用純化的抗原包被微孔板，制成固相抗原，往包被單抗的微孔中依次加入磷脂酰肌醇抗體IgM(PIAb-IgM),再與HRP標(biāo)記的抗原結(jié)合，形成抗原-抗體-酶標(biāo)抗原復(fù)合物，經(jīng)過徹底洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉(zhuǎn)化成藍(lán)色，并在酸的作用下轉(zhuǎn)化成最終的黃色。顏色的深淺和樣品中的磷脂酰肌醇抗體IgM(PIAb-IgM)呈正相關(guān)。用酶標(biāo)儀在450nm波長下測定吸光度(OD值)，通過標(biāo)準(zhǔn)曲線計算樣品中人磷脂酰肌醇抗體IgM(PIAb-IgM)含量。試劑盒組成：試劑盒組成48孔配置96孔配置保存說明書1份1份封板膜2片(48)2片(96)密封袋1個1個酶標(biāo)包被板1X481X962-8°C保存標(biāo)準(zhǔn)品：72ng/L0.5mlX1瓶0.5mlX1瓶2-8°C保存標(biāo)準(zhǔn)品稀釋液1.5mlX1瓶1.5mlX1瓶2-8C保存酶標(biāo)試劑3mlX1瓶6mlX1瓶2-8C保存樣品稀釋液3mlX1瓶6mlX1瓶2-8C保存顯色劑A液3mlX1瓶6mlX1瓶2-8C保存顯色劑B液3mlX1瓶6mlX1瓶2-8C保存終止液3mlX1瓶6mlX1瓶2-8C保存濃縮洗滌液(20mlX20倍)X1瓶(20mlX30倍)X1瓶2-8C保存樣本處理及要求：血清：室溫血液自然凝固10-20分鐘，離心20分鐘左右(2000-3000轉(zhuǎn)/分)。仔細(xì)收集上清，保存過程中如出現(xiàn)沉淀，應(yīng)再次離心。血漿：應(yīng)根據(jù)標(biāo)本的要求選擇EDTA或檸檬酸鈉作為抗凝劑，混合10-20分鐘后，離心20分鐘左右(2000-3000轉(zhuǎn)/分)。仔細(xì)收集上清，保存過程中如有沉淀形成，應(yīng)該再次離心。尿液：用無菌管收集，離心20分鐘左右(2000-3000轉(zhuǎn)/分)。仔細(xì)收集上清，保存過程中如有沉淀形成，應(yīng)再次離心。胸腹水、腦脊液參照實行。細(xì)胞培養(yǎng)上清：檢測分泌性的成份時，用無菌管收集。離心20分鐘左右(2000-3000轉(zhuǎn)/分）。仔細(xì)收集上清。檢測細(xì)胞內(nèi)的成份時，用PBS（PH7.2-7.4）稀釋細(xì)胞懸液，細(xì)胞濃度達(dá)到100萬/ml左右。通過反復(fù)凍融，以使細(xì)胞破壞并放出細(xì)胞內(nèi)成份。離心20分鐘左右（2000-3000轉(zhuǎn)/分）。仔細(xì)收集上清。保存過程中如有沉淀形成，應(yīng)再次離心。組織標(biāo)本：切割標(biāo)本后，稱取重量。加入一定量的PBS，PH7.4。用液氮迅速冷凍保存?zhèn)溆谩?biāo)本融化后仍然保持2-8的溫度。加入一定量的PBS（PH7.4），用手工或勻漿器將標(biāo)本勻漿充分。離心20分鐘左右（2000-3000轉(zhuǎn)/分）。仔細(xì)收集上清。分裝后一份待檢測，其余冷凍備用。標(biāo)本采集后盡早進(jìn)行提取，提取按相關(guān)文獻(xiàn)進(jìn)行，提取后應(yīng)盡快進(jìn)行實驗。若不能馬上進(jìn)行試驗，可將標(biāo)本放于-20°C保存，但應(yīng)避免反復(fù)凍融.不能檢測含NaN3的樣品，因NaN3抑制辣根過氧化物酶的（HRP）活性。操作步驟標(biāo)準(zhǔn)品的稀釋與加樣：在酶標(biāo)包被板上設(shè)標(biāo)準(zhǔn)品孔10孔，在第一、第二孔中分別加標(biāo)準(zhǔn)品100山，然后在第一、第二孔中加標(biāo)準(zhǔn)品稀釋液50山，混勻；然后從第一孔、第二孔中各取100山分別加到第三孔和第四孔，再在第三、第四孔分別加標(biāo)準(zhǔn)品稀釋液50卩1,混勻；然后在第三孔和第四孔中先各取50卩1棄掉，再各取50山分別加到第五、第六孔中，再在第五、第六孔中分別加標(biāo)準(zhǔn)品稀釋液50ul，混勻；混勻后從第五、第六孔中各取50山分別加到第七、第八孔中，再在第七、第八孔中分別加標(biāo)準(zhǔn)品稀釋液50山，混勻后從第七、第八孔中分別取50卩1加到第九、第十孔中，再在第九第十孔分別加標(biāo)準(zhǔn)品稀釋液50卩1，混勻后從第九第十孔中各取50卩1棄掉。（稀釋后各孔加樣量都為50卩1,濃度分別為48ng/L，32ng/L，16ng/L，8ng/L，4ng/L）。加樣：分別設(shè)空白孔（空白對照孔不加樣品及酶標(biāo)試劑，其余各步操作相同）、待測樣品孔。在酶標(biāo)包被板上待測樣品孔中先加樣品稀釋液40卩1,然后再加待測樣品10山（樣品最終稀釋度為5倍）。加樣將樣品加于酶標(biāo)板孔底部，盡量不觸及孔壁，輕輕晃動混勻。溫育：用封板膜封板后置37C溫育30分鐘。配液：將30（48T的20倍）倍濃縮洗滌液用蒸餾水30（48T的20倍）倍稀釋后備用。洗滌：小心揭掉封板膜，棄去液體，甩干，每孔加滿洗滌液，靜置30秒后棄去，如此重復(fù)5次，拍干。加酶：每孔加入酶標(biāo)試劑50卩1，空白孔除外。溫育：操作同3。洗滌：操作同5。顯色：每孔先加入顯色劑A50yl，再加入顯色劑B50yl，輕輕震蕩混勻，37C避光顯色15分鐘.終止：每孔加終止液50gl，終止反應(yīng)（此時藍(lán)色立轉(zhuǎn)黃色）。測定：以空白空調(diào)零，450nm波長依序測量各孔的吸光度（OD值）。測定應(yīng)在加終止液后15分鐘以內(nèi)進(jìn)行。注意事項：1．試劑盒從冷藏環(huán)境中取出應(yīng)在室溫平衡15-30分鐘后方可使用，酶標(biāo)包被板開封后如未用完，板條應(yīng)裝入密封袋中保存。2．濃洗滌液可能會有結(jié)晶析出，稀釋時可在水浴中加溫助溶，洗滌時不影響結(jié)果。3．各步加樣均應(yīng)使用加樣器，并經(jīng)常校對其準(zhǔn)確性，以避免試驗誤差。一次加樣時間最好控制在5分鐘內(nèi)，如標(biāo)本數(shù)量多，推薦使用排槍加樣。請每次測定的同時做標(biāo)準(zhǔn)曲線，最好做復(fù)孔。如標(biāo)本中待測物質(zhì)含量過高（樣本OD值大于標(biāo)準(zhǔn)品孔第一孔的OD值），請先用樣品稀釋液稀釋一定倍數(shù)伍倍）后再測定，計

算時請最后乘以總稀釋倍數(shù)（XnX5）o5．封板膜只限一次性使用，以避免交叉污染。6．底物請避光保存。7．嚴(yán)格按照說明書的操作進(jìn)行，試驗結(jié)果判定必須以酶標(biāo)儀讀數(shù)為準(zhǔn).8．所有樣品，洗滌液和各種廢棄物都應(yīng)按傳染物處理。9．本試劑不同批號組分不得混用。10.如與英文說明書有異，以英文說明書為準(zhǔn)。計算：以標(biāo)準(zhǔn)物的濃度為橫坐標(biāo)，OD值為縱坐標(biāo),在坐標(biāo)紙上繪出標(biāo)準(zhǔn)曲線，根據(jù)樣品的OD值由標(biāo)準(zhǔn)曲線查出相應(yīng)的濃度；再乘以稀釋倍數(shù)；或用標(biāo)準(zhǔn)物的濃度與OD值計算出標(biāo)準(zhǔn)曲線的直線回歸方程式，將樣品的OD值代入方程式，計算出樣品濃度，再乘以稀釋倍數(shù)，即為樣品的實際濃度。試劑盒性能：樣品線性回歸與預(yù)期濃度相關(guān)系數(shù)R值為0.95以上。批內(nèi)與批間應(yīng)分別小于9%和11%檢測范圍：1ng/L-65ng/L保存條件及有效期：1?試劑盒保存:;2-8°C。2．有效期：6個月RDHumanPIAb-IgMFORRESEARCHUSEONLYDrugNamesGenericName：HumanPIAb-IgMELISAKit.PurposeThiskitallowsforthedeterminationofPIAb-IgMconcentrationsinHumanserum,bloodplasma,andotherbiologicalfluids.PrincipleoftheassayThekitassayHumanPIAb-IgMlevelinthesample，usePurifiedantigentocoatmicrotiterplatewells,makesolid-phaseantigen,thenaddPIAb-IgMtowells,CombinedantigenwhichWithHRPlabeled,becomeantigen-antibody-enzyme-antigencomplex,afterwashingCompletely,AddTMBsubstratesolution,TMBsubstratebecomesbluecolorAtHRPenzyme-catalyzed,reactionisterminatedbytheadditionofasulphuricacidsolutionandthecolorchangeismeasuredspectrophotometricallyatawavelengthof450nm.TheconcentrationofPIAb-IgMinthesamplesisthendeterminedbycomparingtheO.D.ofthesamplestothestandardcurve.MaterialsprovidedwiththekitMaterialsprovidedwiththekit48determinations96determinationsStorageUsermanual11Closureplatemembrane22Sealedbags11Microelisastripplate112-8°CStandard：72ng/L0.5mlx1bottle0.5mlx1bottle2-8°CStandarddiluent1.5mlx1bottle1.5mlx1bottle2-8CHRP-Conjugatereagent3mlx1bottle6mlx1bottle2-8CSamplediluent3mlx1bottle6mlx1bottle2-8CChromogenSolutionA3mlx1bottle6mlx1bottle2-8CChromogenSolutionB3mlx1bottle6mlx1bottle2-8CStopSolution3mlx1bottle6mlx1bottle2-8Cwashsolution(20mlx20fold)xibottle(20mlx30fold)x1bottle2-8CSpecimenrequirementsserum-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.Tissuesample-sAftercuttingsamples,checktheweight,addPBS(PH7.2-7.4),Rapidlyfrozenwithliquidnitrogen,maintainsamplesat2-8°Caftermelting,addPBS(PH7.4),HomogenizedbyhandorGrinders,centrifugation20-minatthespeedof2000-3000r.p.m.removesupernatant.extractassoonaspossibleafterSpecimencollection,andaccordingtotherelevantliterature,andshouldbeexperimentassoonaspossibleaftertheextraction.Ifitcan't,specimencanbekeptin-20Ctopreserve,Avoidrepeatedfreeze-thawcycles.Can'tdetectthesamplewhichcontainNaN3,becauseNaN3inhibitsHRPactive.AssayprocedureDiluteandaddsampletoStandard:set10StandardwellsontheELISAplatescoated,addStandard100pltothefirstandthesecondwell,thenaddStandarddilution50pltothefirstandthesecondwell,mix;takeout100plformthefirstandthesecondwellthenaddittothethirdandtheforthwellseparately.thenaddStandarddilution50pltothethirdandtheforthwell,mix;thentakeout50plfromthethirdandtheforthwelldiscard,add50pltothefifthandthesixthwell,thenaddStandarddilution50pltothefifthandthesixthwell,mix;takeout50plfromthefifthandthesixthwellandaddtotheseventhandtheeighthwell,thenaddStandarddilution50pltotheseventhandtheeighthwell,mix;takeout50plfromtheseventhandtheeighthwellandaddtotheninthandthetenthwell,addStandarddilution50pltotheninthandthetenthwell,mix,takeout50plfromtheninthandthetenthwelldiscard(addSample50pltoeachwellafterDiluting,(density:48ng/L，32ng/L，16ng/L，8ng/L，4ng/L)addsample：Setblankwellsseparately(blankcomparisonwellsdon'taddsampleandHRP-Conjugatereagent,othereachstepoperationissame).testingsamplewell.addSampledilution40pltotestingsamplewell,thenaddtestingsample10pl(samplefinaldilutionis5-fold),addsampletowells,don'ttouchthewellwallasfaraspossible,andGentlymix.3.Incubate:AfterclosingplatewithClosureplatemembrane,incubatefor30minat37C.Configurateliquid:30-fold(or20-fold)washsolutiondiluted30-fold(or20-fold)withdistilledwaterandreserve.washing：UncoverClosureplatemembrane,discardLiquid,drybyswing,addwashingbuffertoeverywell,stillfor30sthendrain,repeat5times,drybypat.addenzyme：AddHRP-Conjugatereagent50pltoeachwell,exceptblankwell.7.incubate：Operationwith3.washing：Operationwith5.color：AddChromogenSolutionA50ulandChromogenSolutionBtoeachwell,evadethelightpreservationfor15minat37°C10Sopthereaction:A
