特異性
本試劑盒用于檢測半乳糖凝集素9(GAL9)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(jīng)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半乳糖凝集素9(GAL9)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) | 96-105 | 102 |
EDTA plasma(n=5) | 84-99 | 93 |
heparin plasma(n=5) | 91-103 | 96 |
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半乳糖凝集素9(GAL9)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半乳糖凝集素9(GAL9)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) | 86-94% | 96-103% | 96-103% | 95-104% |
EDTA plasma(n=5) | 78-89% | 80-95% | 94-102% | 89-103% |
heparin plasma(n=5) | 85-99% | 94-101% | 82-89% | 80-105% |
穩(wěn)定性
經(jīng)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)標準品或樣本100μL及磁珠10μL,
37°C酶標板振蕩器孵育90分鐘;
3. 磁吸甩干,加檢測溶液A100μL,37°C酶標板振蕩器孵育60分鐘;
4. 磁吸洗板3次;
5. 加檢測溶液B100μL,37°C振動孵育30分鐘;
6. 磁吸洗板3次;
7. 加鞘液100μL,旋渦震蕩2分鐘后讀數(shù)。
實驗原理
將半乳糖凝集素9(GAL9)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,其中的半乳糖凝集素9(GAL9)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結合,然后加入生物素化的半乳糖凝集素9(GAL9)等多因子檢測試劑盒(流式熒光發(fā)光法)抗體,將未結合的生物素化抗體洗凈后,加入PE標記的親和素,再次徹底洗滌后即可上機讀數(shù)。MFI值和樣品中的半乳糖凝集素9(GAL9)等多因子檢測試劑盒(流式熒光發(fā)光法)呈正相關。
