特異性

本試劑盒用于檢測(cè)天冬氨酸轉(zhuǎn)氨酶(AST),經(jīng)檢測(cè)與其它相似物質(zhì)無(wú)明顯交叉反應(yīng)。
由于受到技術(shù)及樣本來(lái)源的限制,不可能完成對(duì)所有相關(guān)或相似物質(zhì)交叉反應(yīng)檢測(cè),因此本試劑盒有可能與未經(jīng)檢測(cè)的其它物質(zhì)有交叉反應(yīng)。

回收率

分別于定值血清及血漿樣本中加入一定量的天冬氨酸轉(zhuǎn)氨酶(AST)(加標(biāo)樣品),重復(fù)測(cè)定并計(jì)算其均值,回收率為測(cè)定值與理論值的比率。

樣本 回收率范圍(%) 平均回收率(%)
serum(n=5) 90-97 94
EDTA plasma(n=5) 80-88 84
heparin plasma(n=5) 79-90 84

精密度

精密度用樣品測(cè)定值的變異系數(shù)CV表示。CV(%) = SD/mean×100
批內(nèi)差:取同批次試劑盒對(duì)低、中、高值定值樣本進(jìn)行定量檢測(cè),每份樣本連續(xù)測(cè)定20 次,分別計(jì)算不同濃度樣本的平均值及SD值。
批間差:選取3個(gè)不同批次的試劑盒分別對(duì)低、中、高值定值樣本進(jìn)行定量測(cè)定,每個(gè)樣本使用同一試劑盒重復(fù)測(cè)定8次,分別計(jì)算不同濃度樣本的平均值及SD值。
批內(nèi)差: CV<10%
批間差: CV<12%

線性

在定值血清及血漿樣本內(nèi)加入適量的天冬氨酸轉(zhuǎn)氨酶(AST),并倍比稀釋成1:2,1:4,1:8,1:16的待測(cè)樣本,線性范圍即為稀釋后樣本中天冬氨酸轉(zhuǎn)氨酶(AST)含量的測(cè)定值與理論值的比率。

樣本 1:2 1:4 1:8 1:16
serum(n=5) 80-102% 81-103% 82-92% 85-97%
EDTA plasma(n=5) 83-93% 90-104% 98-105% 94-101%
heparin plasma(n=5) 84-104% 94-102% 83-103% 92-103%

穩(wěn)定性

經(jīng)測(cè)定,試劑盒在有效期內(nèi)按推薦溫度保存,其活性降低率小于5%。
為減小外部因素對(duì)試劑盒破壞前后檢測(cè)值的影響,實(shí)驗(yàn)室的環(huán)境條件需盡量保持一致,尤其是實(shí)驗(yàn)室內(nèi)溫度、濕度及溫育條件。其次由同一實(shí)驗(yàn)員來(lái)進(jìn)行操作可減少人為誤差。

實(shí)驗(yàn)流程

1. 實(shí)驗(yàn)前標(biāo)準(zhǔn)品、試劑及樣本的準(zhǔn)備;
2. 加樣(標(biāo)準(zhǔn)品及樣本)100µL,37°C孵育1小時(shí);
3. 吸棄,加檢測(cè)溶液A100µL,37°C孵育1小時(shí);
4. 洗板3次;
5. 加檢測(cè)溶液B100µL,37°C孵育30分鐘;
6. 洗板5次;
7. 加TMB底物90µL,37°C孵育10-20分鐘;
8. 加終止液50µL,立即450nm讀數(shù)。

實(shí)驗(yàn)原理

將天冬氨酸轉(zhuǎn)氨酶(AST)抗體包被于96孔微孔板中,制成固相載體,向微孔中分別加入標(biāo)準(zhǔn)品或標(biāo)本,其中的天冬氨酸轉(zhuǎn)氨酶(AST)與連接于固相載體上的抗體結(jié)合,然后加入生物素化的天冬氨酸轉(zhuǎn)氨酶(AST)抗體,將未結(jié)合的生物素化抗體洗凈后,加入HRP標(biāo)記的親和素,再次徹底洗滌后加入TMB底物顯色。TMB在過(guò)氧化物酶的催化下轉(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天冬氨酸轉(zhuǎn)氨酶(AST)呈正相關(guān)。用酶標(biāo)儀在450nm波長(zhǎng)下測(cè)定吸光度(O.D.值),計(jì)算樣品濃度。
