特異性
本試劑盒用于檢測干擾素α(IFNa)檢測試劑盒(酶聯(lián)免疫吸附試驗法,快捷型)，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干擾素α(IFNa)檢測試劑盒(酶聯(lián)免疫吸附試驗法,快捷型)（加標(biāo)樣品），重復(fù)測定并計算其均值，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) | 99-105 | 102 |
| EDTA plasma(n=5) | 80-96 | 86 |
| heparin plasma(n=5) | 90-99 | 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，分別計算不同濃度樣本的平均值及SD值。
批間差：選取3個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，每個樣本使用同一試劑盒重復(fù)測定8次，分別計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)加入適量的干擾素α(IFNa)檢測試劑盒(酶聯(lián)免疫吸附試驗法,快捷型)，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干擾素α(IFNa)檢測試劑盒(酶聯(lián)免疫吸附試驗法,快捷型)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) | 88-96% | 86-97% | 98-105% | 81-101% |
| EDTA plasma(n=5) | 84-102% | 94-105% | 79-103% | 87-94% |
| heparin plasma(n=5) | 81-101% | 85-98% | 78-102% | 78-94% |
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，實驗室的環(huán)境條件需盡量保持一致，尤其是實驗室內(nèi)溫度、濕度及溫育條件。其次由同一實驗員來進(jìn)行操作可減少人為誤差。
實驗流程
1. 實驗前標(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溫育30分鐘;
3. 甩干，加檢測溶液A100µL，37°C溫育30分鐘;
4. 洗板3次；
5. 加檢測溶液B100µL， 37°C孵育10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)。
實驗原理
將干擾素α(IFNa)檢測試劑盒(酶聯(lián)免疫吸附試驗法,快捷型)單克隆抗體包被于96孔微孔板中，制成固相載體，向微孔中加入標(biāo)準(zhǔn)品或標(biāo)本以及同時加入HRP標(biāo)記干擾素α(IFNa)檢測試劑盒(酶聯(lián)免疫吸附試驗法,快捷型)的多克隆抗體，孵育結(jié)束徹底洗滌后加入TMB底物顯色。TMB在過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被檢測物濃度呈正相關(guān)。用酶標(biāo)儀在450nm波長下測定吸光度(O.D.值)，計算樣品濃度。
