補(bǔ)體成分5a(C5a)等多因子檢測試劑盒(流式熒光法)
Multiplex Assay Kit for Complement Component 5a (C5a) ,etc. by CBA (Cytometric Bead Array)
特異性
本試劑盒用于檢測補(bǔ)體成分5a(C5a)等多因子檢測試劑盒(流式熒光法),經(jīng)檢測與其它相似物質(zhì)無明顯交叉反應(yīng)。
由于受到技術(shù)及樣本來源的限制,不可能完成對所有相關(guān)或相似物質(zhì)交叉反應(yīng)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(yīng)。
回收率
分別于定值血清及血漿樣本中加入一定量的補(bǔ)體成分5a(C5a)等多因子檢測試劑盒(流式熒光法)(加標(biāo)樣品),重復(fù)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) | 80-97 | 83 |
| EDTA plasma(n=5) | 85-99 | 93 |
| 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(jìn)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(jìn)行定量測定,每個樣本使用同一試劑盒重復(fù)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)加入適量的補(bǔ)體成分5a(C5a)等多因子檢測試劑盒(流式熒光法),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補(bǔ)體成分5a(C5a)等多因子檢測試劑盒(流式熒光法)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) | 93-105% | 97-104% | 88-104% | 85-105% |
| EDTA plasma(n=5) | 93-101% | 88-97% | 94-101% | 79-101% |
| heparin plasma(n=5) | 79-88% | 79-93% | 78-91% | 99-105% |
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(jìn)行操作可減少人為誤差。
實驗流程
1、向?qū)嶒灠迕靠變?nèi)加入200μL分析緩沖液以預(yù)濕;
2、實驗前標(biāo)準(zhǔn)品、試劑及樣本準(zhǔn)備;
3、加樣(標(biāo)準(zhǔn)品、樣本、磁珠),標(biāo)準(zhǔn)品或樣本100μL及磁珠10μL,25°C酶標(biāo)板振蕩器孵育2小時;
4、磁吸甩干,加檢測溶液A 100μL,25°C酶標(biāo)板振蕩器孵育1小時;
5、磁吸甩干,加檢測溶液B 100μL,25°C振動孵育30分鐘;
6、磁吸洗板1次;
7、加鞘液100μL,旋渦震蕩10分鐘后讀數(shù)。
實驗原理
將補(bǔ)體成分5a(C5a)等多因子檢測試劑盒(流式熒光法)抗體包被于磁性微球表面,制成固相載體,向微孔中分別加入標(biāo)準(zhǔn)品或標(biāo)本以及磁珠,其中的補(bǔ)體成分5a(C5a)等多因子檢測試劑盒(流式熒光法)與連接于固相載體上的抗體結(jié)合,然后加入生物素化的補(bǔ)體成分5a(C5a)等多因子檢測試劑盒(流式熒光法)抗體,加入PE標(biāo)記的親和素,用流式細(xì)胞儀讀數(shù)。MFI值和樣品中的補(bǔ)體成分5a(C5a)等多因子檢測試劑盒(流式熒光法)濃度呈正相關(guān)。
