2.    加(jia)(jia)樣(yang):分別(bie)設空白(bai)孔(kong)(空白(bai)對照孔(kong)不(bu)加(jia)(jia)樣(yang)品(pin)(pin)及(ji)酶(mei)(mei)標(biao)(biao)試劑,其(qi)余各(ge)步操(cao)作相同)、待測(ce)(ce)(ce)樣(yang)品(pin)(pin)孔(kong)。在酶(mei)(mei)標(biao)(biao)包被板上待測(ce)(ce)(ce)樣(yang)品(pin)(pin)孔(kong)中先(xian)加(jia)(jia)樣(yang)品(pin)(pin)稀釋液(ye)40μl,然后再(zai)加(jia)(jia)待測(ce)(ce)(ce)樣(yang)品(pin)(pin)10μl(樣(yang)品(pin)(pin)zui終稀釋度為5倍)。加(jia)(jia)樣(yang)將(jiang)樣(yang)品(pin)(pin)加(jia)(jia)于(yu)酶(mei)(mei)標(biao)(biao)板孔(kong)底部,盡量不(bu)觸及(ji)孔(kong)壁,輕輕晃動混(hun)勻。

3.    溫育:用封板膜封板后置37℃溫(wen)育30分鐘。

4.    配(pei)液:將30(48T的20倍(bei)(bei)(bei))倍(bei)(bei)(bei)濃縮洗滌液用蒸餾水30(48T的20倍(bei)(bei)(bei))倍(bei)(bei)(bei)稀釋(shi)后備用。

5.    洗(xi)滌(di):小心揭掉封(feng)板膜,棄(qi)去液體,甩(shuai)干,每孔(kong)加(jia)滿洗(xi)滌(di)液,靜(jing)置30秒后棄(qi)去,如此重復5次,拍干。

6.    加酶:每孔加入酶標(biao)試劑(ji)50μl,空(kong)白孔除外。

7.    溫育:操作(zuo)同(tong)3。

8.    洗滌:操(cao)作同5。

9.    顯色(se):每孔先加(jia)入顯色(se)劑A50μl,再加(jia)入顯色(se)劑B50μl,輕輕震(zhen)蕩(dang)混勻,37℃避光顯色(se)15分鐘.

10.終(zhong)止:每(mei)孔加終(zhong)止液50μl,終(zhong)止反應(此時藍(lan)色立轉黃色)。

測定:以空(kong)白空(kong)調零,450nm波長依序測量各孔的吸光度(OD值)。 測定應在加終止液后15分鐘以內進行。

計(ji)算(suan):

以標(biao)準物(wu)的(de)(de)濃(nong)度為橫坐(zuo)(zuo)標(biao),OD值為縱坐(zuo)(zuo)標(biao),在坐(zuo)(zuo)標(biao)紙(zhi)上繪出標(biao)準曲線,根據樣品的(de)(de)OD值由(you)標(biao)準曲線查出相應的(de)(de)濃(nong)度;再(zai)乘以稀釋倍數(shu);或用標(biao)準物(wu)的(de)(de)濃(nong)度與OD值計算出標(biao)     

準曲線(xian)的直(zhi)線(xian)回歸方程式(shi),將樣(yang)品(pin)的OD值(zhi)代入方程式(shi),計(ji)算出樣(yang)品(pin)濃度,再(zai)乘以稀釋(shi)     

倍數,即為(wei)樣品的實際濃度(du)。

注(zhu)意事項:

1.       試劑盒從冷藏環境中取出應(ying)在室溫(wen)平衡(heng)15-30分鐘(zhong)后(hou)方可使用,酶(mei)標(biao)包被(bei)板(ban)開封后(hou)如(ru)未用完(wan),板(ban)條(tiao)應(ying)裝(zhuang)入(ru)密封袋中保(bao)存。

2.     濃洗(xi)滌(di)液可能會有結晶析出,稀釋(shi)時(shi)可在水(shui)浴中加溫助(zhu)溶,洗(xi)滌(di)時(shi)不影響結果。

3.     各步加樣均應使用加樣器,并經常校對其準(zhun)確(que)性,以避免試驗誤(wu)差。一次加樣時(shi)間控(kong)制在5分(fen)鐘內,如標本(ben)數量多(duo),推薦使用排槍加樣。

4.     請(qing)每次(ci)測定的同時做(zuo)標(biao)準(zhun)曲線,做(zuo)復孔。如標(biao)本(ben)中(zhong)待測物(wu)質含量過高(樣本(ben)OD值(zhi)大于標(biao)準(zhun)品孔*孔的OD值(zhi)),請(qing)先用樣品稀釋液(ye)稀釋一定倍數(n倍)后再測定,計算時請(qing)zui后乘以總(zong)稀釋倍數(×n×5)。

5.     封板(ban)膜只限一次性使用,以避免交叉污(wu)染。

6.     底(di)物(wu)請避光保存。

7.     嚴格按(an)照(zhao)說明書(shu)的操(cao)作進(jin)行,試驗(yan)結(jie)果判定必須(xu)以酶(mei)標(biao)儀讀數為準.

8.     所有樣品,洗滌(di)液和各種廢棄(qi)物(wu)都應按(an)傳染(ran)物(wu)處理。

9.     本(ben)試劑不同批號組(zu)分不得(de)混用。

樣本處理及要求:
