特點(diǎn)
一、高效、靈敏、特異的抗體；
二、穩(wěn)定的重復(fù)性和可靠性；
三、吸附性能好,空白值低,孔底透明度高的固相載體；
四、適用血清、血漿、組織勻漿液、細(xì)胞培養(yǎng)上清液、尿液等等多種標(biāo)本類型；
五、節(jié)省實(shí)驗(yàn)經(jīng)費(fèi).
elisa試劑盒回收率是反應(yīng)待測物在樣品分析過程中的損失的程度,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,就是說你的回收率是99%,這個與真實(shí)成分有密切的關(guān)系,說明方法的準(zhǔn)確度.比如水中總無機(jī)氯含量測定,樣品水中含有無機(jī)氯20mg/L,取100mL被測水樣品,加入0.1mL濃度為10mg/mL的含無機(jī)氯標(biāo)準(zhǔn)樣品,測定時忽略體積變化,如果測定出樣品中無機(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)對屠宰場進(jìn)行臨床檢測.該方法簡單、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,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.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,檢測前先離心或過濾.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.

操作方法
雙抗體夾心法
1.包被：用0.05MPH9.牰碳酸鹽包被緩沖液將抗體稀釋蛋白質(zhì)含量為1～10μg/ml.在每個聚苯乙烯板的反應(yīng)孔中加0.1ml,4℃隔夜.次日,棄去孔內(nèi)溶液,用洗滌緩沖液洗3次,每次3分鐘.（簡稱洗滌,下同）.
2. 加樣：加一定稀釋的待檢樣品0.1ml于上述已包被之反應(yīng)孔中,置37℃孵育1小時.然后洗滌.（同時做空白孔,陰性對照孔及陽性對照孔）.
3. 加酶標(biāo)抗體：于各反應(yīng)孔中,加入新鮮稀釋的酶標(biāo)抗體（經(jīng)滴定后的稀釋度）0.1ml.37℃孵育0.5～1小時,洗滌.
4. 加底物液顯色：于各反應(yīng)孔中加入臨時配制的TMB底物溶液0.1ml,37℃10～30分鐘.
5. 終止反應(yīng)：于各反應(yīng)孔中加入2M硫酸0.05ml.
6. 結(jié)果判定：可于白色背景上,直接用肉眼觀察結(jié)果：反應(yīng)孔內(nèi)顏色越深,陽性程度越強(qiáng),陰性反應(yīng)為無色或極淺,依據(jù)所呈顏色的深淺,以“+"、“-"號表示.也可測OD值：在ELISA檢測儀上,于450nm（若以ABTS顯色,則410nm）處,以空白對照孔調(diào)零后測各孔OD值,若大于規(guī)定的陰性對照OD值的2.1倍,即為陽性.
間接法
1.用包被緩沖液將已知抗原稀釋1～10μg/ml,每孔加0.1ml,4℃隔夜；
2.次日洗滌3次；
3.加一定稀釋的待檢樣品（未知抗體）0.1ml于上述已包被之反應(yīng)孔中,置37℃孵育1小時,洗滌；
4.（同時做空白、陰性及陽性孔對照）于反應(yīng)孔中,加入新鮮稀釋的酶標(biāo)第二抗體（抗抗體）0.1ml；
5.37℃孵育35-60分鐘,洗滌；
6.’zui后一遍用DDW洗滌.
其余步驟同“雙抗體夾心法"的4、5、6.
發(fā)展前景
臨床測定技術(shù)的發(fā)展主要在于方法學(xué)的發(fā)展,而方法學(xué)的發(fā)展依托于試劑生產(chǎn)技術(shù)不斷進(jìn)步更新和型標(biāo)記物的應(yīng)用.分子生物學(xué)正在并zui終肯定會讓對整個生命科學(xué)有一個全面而*的認(rèn)識,其對免疫測定技術(shù)發(fā)展的影響也是直接而又有效的,對以前一些難以檢測的生物活性物質(zhì)的測定,并且大大提高了檢測的靈敏度和特異性.
應(yīng)用領(lǐng)域
ELISA法是免疫診斷中的一項(xiàng)新技術(shù),現(xiàn)已成功地應(yīng)用于多種病原微生物所引起的傳染病、寄生蟲病及非傳染病等方面的免疫診斷.也已應(yīng)用于大分子抗原和小分子抗原的定量測定,根據(jù)已經(jīng)使用的結(jié)果,認(rèn)為ELISA法具有靈敏、特異、簡單、快速、穩(wěn)定及易于自動化操作等特點(diǎn).不僅適用于臨床標(biāo)本的檢查,而且由于一天之內(nèi)可以檢查幾百甚上千份標(biāo)本,因此,也適合于血清流行病學(xué)調(diào)查.本法不僅可以用來測定抗體,而且也可用于測定體液中的循環(huán)抗原,所以也是一種早期診斷的良好方法.因此ELISA法在生物醫(yī)學(xué)各領(lǐng)域的應(yīng)用范圍日益擴(kuò)大,
可概括四個方面：
1、免疫酶染色各種細(xì)胞內(nèi)成份的定位.
2、研究抗酶抗體的合成.
3、顯現(xiàn)微量的免疫沉淀反應(yīng).
4、定量檢測體液中抗原或抗體成份.
