(注:單次混測多因子不超過8個指標 )

    • 催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)光法)產(chǎn)品包裝(模擬)
    • 催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)光法)產(chǎn)品包裝(模擬)
    • Certificate通過ISO 9001、ISO 13485質(zhì)量體系認證

    特異性

    本試劑盒用于檢測催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)光法),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(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催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)光法)(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)79-10182
    EDTA plasma(n=5)85-9990
    heparin plasma(n=5)89-9794
    sodium citrate plasma(n=5)79-9893

    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)加入適量的催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)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催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)光法)含量的測定值與理論值的比率。

    樣本1:21:41:81:16
    serum(n=5)80-101%94-101%92-103%85-101%
    EDTA plasma(n=5)90-105%81-96%99-105%78-105%
    heparin plasma(n=5)85-99%82-103%95-102%78-98%
    sodium citrate plasma(n=5)94-102%83-95%80-93%85-103%

    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。

    實驗流程

    1. 實驗前標準品、試劑及樣本準備;
    2. 加樣(標準品、樣本、磁珠、檢測溶液A)標準品或樣本50μL及磁珠10μL,加檢測溶液A50μL,
        37°C酶標板振蕩器孵育60分鐘;
    3. 磁吸洗板3次;
    4. 加檢測溶液B100μL,37°C振動孵育30分鐘;
    5. 磁吸洗板3次;
    6. 加鞘液100μL,旋渦震蕩2分鐘后讀數(shù)。

    實驗原理

    將催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)光法)抗體包被于磁珠,制成固相載體,向微孔中分別加入標準品或標本以及磁珠、標記VEGFA,標記的催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)光法)和未標記的催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)光法)與連接于固相載體上的抗體競爭結(jié)合,然后將未結(jié)合物洗凈后,加入PE標記的親和素,再次徹底洗滌后即可上機讀數(shù)。MFI值和樣品中的催產(chǎn)素(OT)等多因子檢測試劑盒(流式熒光發(fā)光法)呈負相關(guān)。
