特異性
本試劑盒用于檢測白介素1受體拮抗劑(IL1RA),經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白介素1受體拮抗劑(IL1RA)(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) | 97-105 | 101 |
EDTA plasma(n=5) | 80-92 | 85 |
heparin plasma(n=5) | 78-97 | 90 |
精密度
精密度用樣品測定值的變異系數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白介素1受體拮抗劑(IL1RA),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白介素1受體拮抗劑(IL1RA)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) | 96-103% | 84-101% | 97-105% | 87-95% |
EDTA plasma(n=5) | 87-104% | 92-101% | 78-93% | 84-101% |
heparin plasma(n=5) | 98-105% | 83-93% | 82-101% | 97-104% |
穩(wěn)定性
經測定,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)100µL,37°C孵育1小時;
3. 吸棄,加檢測溶液A100µL,37°C孵育1小時;
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TMB底物90µL,37°C孵育10-20分鐘;
8. 加終止液50µL,立即450nm讀數。
實驗原理
將白介素1受體拮抗劑(IL1RA)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,其中的白介素1受體拮抗劑(IL1RA)與連接于固相載體上的抗體結合,然后加入生物素化的白介素1受體拮抗劑(IL1RA)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TMB底物顯色。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。顏色的深淺和樣品中的白介素1受體拮抗劑(IL1RA)呈正相關。用酶標儀在450nm波長下測定吸光度(O.D.值),計算樣品濃度。
