特異性

本試劑盒用于檢測Ⅱ型前膠原羧基端原肽(PIICP),經(jīng)檢測與其它相似物質無明顯交叉反應。
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Ⅱ型前膠原羧基端原肽(PIICP)(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) 94-101 97
EDTA plasma(n=5) 90-101 93
heparin plasma(n=5) 84-97 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。
批內差: CV<10%
批間差: CV<12%

線性

在定值血清及血漿樣本內加入適量的Ⅱ型前膠原羧基端原肽(PIICP),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Ⅱ型前膠原羧基端原肽(PIICP)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) 84-101% 78-104% 85-104% 84-93%
EDTA plasma(n=5) 88-105% 93-103% 79-94% 97-104%
heparin plasma(n=5) 88-101% 97-104% 80-92% 86-93%

穩(wěn)定性

經(jīng)測定,試劑盒在有效期內按推薦溫度保存,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。

實驗流程

1. 實驗前標準品、試劑及樣本的準備;
2. 加樣(標準品及樣本)50µL,
    加入50µL檢測液A(臨用前配制);
    37°C溫育1小時。
3. 洗板3次;
4. 加檢測溶液B100µL,37°C孵育30分鐘;
5. 洗板5次;
6. 加TMB底物90µL,37°C孵育10-20分鐘;
7. 加終止液50µL,立即450nm讀數(shù)。

實驗原理

本試劑盒應用競爭抑制酶聯(lián)免疫分析法測定標本中待測物質水平。將Ⅱ型前膠原羧基端原肽(PIICP)單克隆抗體包被微孔板,制成固相載體,往包被抗體的微孔中同時加入生物素標記的抗原和待測抗原(標準品或樣本),待測抗原與生物素標記抗原對特異性抗體進行競爭結合。溫育后經(jīng)洗滌去掉未結合物,然后加入HRP標記的親和素,經(jīng)過溫育和徹底洗滌后加入底物TMB顯色。TMB在過氧化物酶的催化下轉化成藍色,并在酸的作用下轉化成最終的黃色。待測標本濃度越高,標記抗原和抗體的結合就越受到抑制,顯色愈淺。顯色的深淺與酶量呈正相關,而與樣品中待測物質含量呈負相關。用酶標儀在450nm波長下測定吸光度(O.D.值),計算樣品濃度。
