ELISA試劑盒操作步驟
ELISA試劑盒使用前,將所有試劑充分混勻.不要使液體產(chǎn)生大量的泡沫,以免加樣時加入大量的氣泡,產(chǎn)生加樣上的誤差.
根據(jù)待測樣品數(shù)量加上標(biāo)準(zhǔn)品的數(shù)量決定所需的板條數(shù).每個標(biāo)準(zhǔn)品和空白孔建議做復(fù)孔.每個樣品根據(jù)自己的數(shù)量來定,能使用復(fù)孔的盡量做復(fù)孔.標(biāo)本用標(biāo)本稀釋液1:1稀釋后加入50ul于反應(yīng)孔內(nèi).
加入稀釋好后的標(biāo)準(zhǔn)品50ul于反應(yīng)孔、加入待測樣品50ul于反應(yīng)孔內(nèi).立即加入50ul的生物素標(biāo)記的抗體.蓋上膜板,輕輕振蕩混勻,37℃溫育1小時.
甩去孔內(nèi)液體,每孔加滿洗滌液,振蕩30秒,甩去洗滌液,用吸水紙拍干.重復(fù)此操作3次.如果用洗板機洗滌,洗滌次數(shù)增加一次.
每孔加入80ul的親和鏈酶素-HRP,輕輕振蕩混勻,37℃溫育30分鐘.
甩去孔內(nèi)液體,每孔加滿洗滌液,振蕩30秒,甩去洗滌液,用吸水紙拍干.重復(fù)此操作3次.如果用洗板機洗滌,洗滌次數(shù)增加一次.
每孔加入底物A、B各50ul,輕輕振蕩混勻,37℃溫育10分鐘.避免光照.
取出酶標(biāo)板,迅速加入50ul終止液,加入終止液后應(yīng)立即測定結(jié)果.
在450nm波長處測定各孔的OD值.
ELISA操作步驟
酶聯(lián)免疫吸附實驗材料,試劑,溶液
1.酶標(biāo)板,100μltip頭,1mlEp管,濕盒
2.包被稀釋液(0.05mol/L碳酸鈉-碳酸氫鈉buffer,pH9.6)
碳酸鈉0.15g,碳酸氫鈉0.29g,疊氮鈉0.02g,加雙蒸水100ml,調(diào)pH9.6
3.封閉液(5%小牛血清/PBS溶液)
小牛血清5ml,1*PBS(pH7.4)95ml
4.洗滌液(PBST,pH7.4)
NaCl0.8g,KH2PO40.02g,Na2HPO4.12H2O0.29g,KCl0.02g,Tween200.05ml,疊氮鈉0.01g,加雙蒸水100ml,調(diào)pH7.4
5.樣本稀釋液(PBS,pH7.4)
NaCl0.8g,KH2PO40.02g,Na2HPO4.12H2O0.29g,KCl0.02g,疊氮鈉0.01g,加雙蒸水100ml,調(diào)pH7.4
6.酶標(biāo)第2抗體(羊抗兔)稀釋范圍1:5,000-1:100,000
7.底物液(TMB-過氧化氫尿素溶液)
①底物液A:TMB20mg,無水乙醇10ml,加雙蒸水100ml.
②底物液B(0.1mol/L檸檬酸-0.2mol/L磷酸二氫鈉緩沖液,pH5.0-5.4)
Na2HPO41.46g,檸檬酸0.933g,0.75%過氧化氫尿素0.64ml,加三蒸水100ml,調(diào)pH5.0-5.4
③底物A和B按1:1混合即成TMB-過氧化氫尿素溶液.
8.終止液(2mol/LH2SO4溶液)雙蒸水200ml,濃硫酸34ml,(緩慢滴加并不斷攪拌),加雙蒸水300ml
9.0.9%生理鹽水
操作步驟:
1.包被過程(注意設(shè)置空白對照,陰性對照):
將所用抗原用包被稀釋液稀釋到適當(dāng)濃度(一般所需抗原包被量為每孔20-200μg),每孔抗原加入100μl,置37℃,4h,或4℃,24h;棄去孔中液體.(為避免蒸發(fā),板上應(yīng)加蓋或?qū)迤椒旁诘撞坑袧窦啿嫉慕饘贊窈兄?
2.封閉酶標(biāo)反應(yīng)孔:
5%小牛血清置37℃封閉40min.封閉時將封閉液加滿各反應(yīng)孔,并去除各孔中的氣泡,封閉結(jié)束后用洗滌液滿孔洗滌3遍,每遍3min.
洗滌方法:吸干孔內(nèi)反應(yīng)液,將洗滌液注滿板孔,放置2min略作搖動,吸干孔內(nèi)液,傾去液體后在吸水紙上拍干
洗滌次數(shù)3次
3.加入待檢測樣品(建立合適的濃度梯度):
檢測時一般采用1:50-1:400的稀釋度,應(yīng)采用較大稀釋體積進(jìn)行,一般保證樣品吸取量>20μl.
將稀釋好的樣品加入酶標(biāo)反應(yīng)孔中,每樣品少加雙孔,每孔100μl,置于37℃,40-60min.用洗滌液滿孔洗滌3遍,每遍3min.
4.加入酶標(biāo)抗體:
酶標(biāo)抗體:根據(jù)酶結(jié)合物提供商提供的參考工作稀釋度進(jìn)行.37℃,30-60min之間.短于30min往往結(jié)果不穩(wěn)定.每孔加100μl.洗滌同前.
5.加入底物液(現(xiàn)用現(xiàn)配):
*TMB-過氧化氫尿素溶液,OPD-過氧化氫底物液系統(tǒng)次之.
底物加入量:每孔100μl,置37℃避光放置3-5分鐘,加入終止液顯色.
6.終止反應(yīng):
每孔加入終止液50μl終止反應(yīng),于20min內(nèi)測定實驗結(jié)果.
7.結(jié)果判斷:
OPD顯色后采用492nm波長,TMB反應(yīng)產(chǎn)物檢測需要450nm波長.檢測時一定要首先進(jìn)行空白孔系統(tǒng)調(diào)零.用測定標(biāo)本孔的吸收值與一組陰性標(biāo)本測定孔平均值的比值(P/N)表示,當(dāng)P/N大于2時作為抗體的效價.(數(shù)值的大小依具體檢測要求而定.)
