特異性
本試劑盒用于檢測(cè)S100鈣結(jié)合蛋白A8(S100A8)，經(jīng)檢測(cè)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(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S100鈣結(jié)合蛋白A8(S100A8)（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) | 90-102 | 95 |
| EDTA plasma(n=5) | 90-97 | 93 |
| heparin plasma(n=5) | 97-105 | 101 |
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S100鈣結(jié)合蛋白A8(S100A8)，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S100鈣結(jié)合蛋白A8(S100A8)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) | 90-104% | 88-96% | 91-99% | 80-98% |
| EDTA plasma(n=5) | 95-104% | 78-99% | 96-105% | 88-102% |
| heparin plasma(n=5) | 85-105% | 80-98% | 93-105% | 96-105% |
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S100鈣結(jié)合蛋白A8(S100A8)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S100鈣結(jié)合蛋白A8(S100A8)與連接于固相載體上的抗體結(jié)合，然后加入生物素化的S100鈣結(jié)合蛋白A8(S100A8)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S100鈣結(jié)合蛋白A8(S100A8)呈正相關(guān)。用酶標(biāo)儀在450nm波長下測(cè)定吸光度(O.D.值)，計(jì)算樣品濃度。
