特異性
本試劑盒用于檢測硫氧化還原蛋白(Trx),經(jīng)檢測與其它相似物質(zhì)無明顯交叉反應(yīng)。
由于受到技術(shù)及樣本來源的限制,不可能完成對所有相關(guān)或相似物質(zhì)交叉反應(yīng)檢測,因此本試劑盒有可能與未經(jīng)檢測的其它物質(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硫氧化還原蛋白(Trx)(加標(biāo)樣品),重復(fù)測定并計(jì)算其均值,回收率為測定值與理論值的比率。
樣本 | 回收率范圍(%) | 平均回收率(%) |
serum(n=5) | 83-90 | 87 |
EDTA plasma(n=5) | 82-93 | 88 |
heparin plasma(n=5) | 90-98 | 93 |
精密度
精密度用樣品測定值的變異系數(shù)CV表示。CV(%) = SD/mean×100
批內(nèi)差:取同批次試劑盒對低、中、高值定值樣本進(jìn)行定量檢測,每份樣本連續(xù)測定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低、中、高值定值樣本進(jìn)行定量測定,每個(gè)樣本使用同一試劑盒重復(fù)測定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)加入適量的硫氧化還原蛋白(Trx),并倍比稀釋成1:2,1:4,1:8,1:16的待測樣本,線性范圍即為稀釋后樣本中硫氧化還原蛋白(Trx)含量的測定值與理論值的比率。
樣本 | 1:2 | 1:4 | 1:8 | 1:16 |
serum(n=5) | 81-103% | 91-98% | 83-99% | 80-91% |
EDTA plasma(n=5) | 90-101% | 84-101% | 86-96% | 98-105% |
heparin plasma(n=5) | 98-105% | 82-99% | 90-102% | 86-101% |
穩(wěn)定性
經(jīng)測定,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%。
為減小外部因素對試劑盒破壞前后檢測值的影響,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,加檢測溶液A100μL,37°C孵育1小時(shí);
4. 洗板3次;
5. 加檢測溶液B100µL,37°C孵育30分鐘;
6. 洗板5次;
7. 加底物100µL,37°C孵育10分鐘;
8. 讀數(shù)。
實(shí)驗(yàn)原理
將硫氧化還原蛋白(Trx)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,其中的硫氧化還原蛋白(Trx)與連接于固相載體上的抗體結(jié)合,然后加入生物素化的硫氧化還原蛋白(Trx)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底物。加入底物后會(huì)產(chǎn)生輝光型光信號。發(fā)射光強(qiáng)度和樣品中的硫氧化還原蛋白(Trx)呈正相關(guān)。用化學(xué)發(fā)光儀測定相對光單位(RLU),計(jì)算樣品濃度。
