  • 5-羥色胺(5-HT)等多因子檢測試劑盒(流式熒光發(fā)光法) 產品包裝(模擬)
  • Certificate 通過ISO 9001、ISO 13485質量體系認證

特異性

本試劑盒用于檢測5-羥色胺(5-HT)等多因子檢測試劑盒(流式熒光發(fā)光法),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5-羥色胺(5-HT)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) 83-97 86
EDTA plasma(n=5) 81-101 92
heparin plasma(n=5) 78-90 85
sodium citrate plasma(n=5) 88-102 92

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5-羥色胺(5-HT)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5-羥色胺(5-HT)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 1:2 1:4 1:8 1:16
serum(n=5) 82-97% 94-103% 88-101% 94-102%
EDTA plasma(n=5) 82-97% 97-105% 92-101% 89-96%
heparin plasma(n=5) 79-99% 94-101% 87-101% 92-101%
sodium citrate plasma(n=5) 84-97% 88-98% 85-95% 83-96%

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5-羥色胺(5-HT)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5-羥色胺(5-HT)等多因子檢測試劑盒(流式熒光發(fā)光法)和未標記的5-羥色胺(5-HT)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合,然后將未結合物洗凈后,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5-羥色胺(5-HT)等多因子檢測試劑盒(流式熒光發(fā)光法)呈負相關。
