人妊娠相關(guān)血漿蛋白A(PAPP-A)試劑盒標(biāo)本的采集及保存:
1.血清:室溫血液自然凝固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(guò)程 中 如有沉淀形成,應(yīng)再次離心。
2.血漿:應(yīng)根據(jù)標(biāo)本的要求選擇EDTA、檸檬酸鈉或肝素作為抗凝劑,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(guò)程中如有沉淀形成,應(yīng)再次離心。
3.尿液:用無(wú)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(guò)程中如有沉淀形成,應(yīng)再次離心。胸腹水、腦脊液參照此實(shí)行。
4.細(xì)胞培養(yǎng)上清:檢測(cè)分泌性的成份時(shí),用無(wú)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(cè)細(xì)胞內(nèi)的成份時(shí),用PBS(PH7.2-7.4)稀釋細(xì)胞懸液,細(xì)胞濃度達(dá)到100萬(wàn)/ml左右。通過(guò)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(guò)程中如有沉淀形成,應(yīng)再次離心。
5.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?。?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(cè),其余冷凍備用。
elisa試劑盒回收率是反應(yīng)待測(cè)物在樣品分析過(guò)程中的損失的程度,損失越少,回收率越高,如果作標(biāo)液1PPM,就是1毫克/升,而作出標(biāo)準(zhǔn)數(shù)據(jù)為0.99毫克/升,就是說(shuō)你的回收率是99%,這個(gè)與真實(shí)成分有密切的關(guān)系,說(shuō)明方法的準(zhǔn)確度.比如水中總無(wú)機(jī)氯含量測(cè)定,樣品水中含有無(wú)機(jī)氯20mg/L,取100mL被測(cè)水樣品,加入0.1mL濃度為10mg/mL的含無(wú)機(jī)氯標(biāo)準(zhǔn)樣品,測(cè)定時(shí)忽略體積變化,如果測(cè)定出樣品中無(wú)機(jī)氯為2.98mg/L,則認(rèn)為回收率為99%.
制備方法
包括以下步驟:
1)抗原表位的計(jì)算機(jī)篩選;
2)抗原的制備;
3)血清的采集;
4)間接ELISA方法的建立;
5)間接ELISA方法的敏感性和特異性驗(yàn)證;
6)試劑盒的穩(wěn)定性驗(yàn)證;
7)對(duì)屠宰場(chǎng)進(jìn)行臨床檢測(cè).該方法簡(jiǎn)單、快速、靈敏度高、特異性強(qiáng)、穩(wěn)定性合格、重復(fù)性好.應(yīng)用本發(fā)明制得的試劑盒能有效檢出感染豬的戊型肝炎病毒,適用于大批量發(fā)病樣本的檢測(cè),可用于豬戊肝的快速診斷,并預(yù)防、控制豬戊肝病毒的流行和阻斷戊肝病毒由豬向人傳播.
組成結(jié)構(gòu)
1、血清:操作過(guò)程中避免任何細(xì)胞刺激.使用不含熱原和內(nèi)毒素的試管.收集血液后,1000×g離心10分鐘將血紅細(xì)胞迅速小心地分離.
2、血漿:EDTA、檸檬酸鹽、肝素血漿可用于檢測(cè).1000×g離心30分鐘去除顆粒.
3、細(xì)胞上清液:1000×g離心10分鐘去除顆粒和聚合物.
4、組織勻漿:將組織加入適量生理鹽水搗碎.1000×g離心10分鐘,取上清液.
5、保存:如果樣品不立即使用,應(yīng)將其分成小部分-70℃保存,避免反復(fù)冷凍.盡可能的不要使用溶血或高血脂血.如果血清中大量顆粒,檢測(cè)前先離心或過(guò)濾.不要在37℃或更高的溫度加熱解凍.應(yīng)在室溫下解凍并確保樣品均勻地充分解凍.
