特異性
本試劑盒用于檢測基質(zhì)金屬蛋白酶2(MMP2)，經(jīng)檢測與其它相似物質(zhì)無明顯交叉反應。
由于受到技術及樣本來源的限制，不可能完成對所有相關或相似物質(zhì)交叉反應檢測，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。
回收率
分別于定值血清及血漿樣本中加入一定量的基質(zhì)金屬蛋白酶2(MMP2)（加標樣品），重復測定并計算其均值，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 |
| heparin plasma(n=5) | 96-104 | 101 |
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、高值定值樣本進行定量測定，每個樣本使用同一試劑盒重復測定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)加入適量的基質(zhì)金屬蛋白酶2(MMP2)，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基質(zhì)金屬蛋白酶2(MMP2)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) | 91-101% | 79-88% | 88-98% | 79-103% |
| heparin plasma(n=5) | 88-102% | 83-93% | 82-99% | 83-93% |
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行操作可減少人為誤差。

7. 加底物100µL，37°C孵育10分鐘；
8. 讀數(shù)。
實驗原理
將基質(zhì)金屬蛋白酶2(MMP2)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準品或標本，其中的基質(zhì)金屬蛋白酶2(MMP2)與連接于固相載體上的抗體結合，然后加入生物素化的基質(zhì)金屬蛋白酶2(MMP2)抗體，將未結合的生物素化抗體洗凈后，加入HRP標記的親和素，再次徹底洗滌后加入底物。加入底物后會產(chǎn)生輝光型光信號。發(fā)射光強度和樣品中的基質(zhì)金屬蛋白酶2(MMP2)呈正相關。用化學發(fā)光儀測定相對光單位（RLU），計算樣品濃度。
