Salusin肽α(SALa)檢測試劑盒(酶聯(lián)免疫吸附試驗法)
ELISA Kit for Salusin Alpha (SALa)
特異性
本試劑盒用于檢測Salusin肽α(SALa),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Salusin肽α(SALa)(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) | 86-99 | 94 |
| EDTA plasma(n=5) | 98-105 | 102 |
| heparin plasma(n=5) | 89-96 | 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Salusin肽α(SALa),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Salusin肽α(SALa)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) | 78-103% | 79-91% | 90-99% | 82-102% |
| EDTA plasma(n=5) | 98-105% | 81-90% | 78-94% | 89-97% |
| heparin plasma(n=5) | 93-105% | 80-92% | 88-103% | 78-101% |
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)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Salusin肽α(SALa)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。溫育后經洗滌去掉未結合物,然后加入HRP標記的親和素,經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。
