Salusin肽α(SALa)等多因子檢測試劑盒(流式熒光法)
Multiplex Assay Kit for Salusin Alpha (SALa) ,etc. by CBA (Cytometric Bead Array)
特異性
本試劑盒用于檢測Salusin肽α(SALa)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Salusin肽α(SALa)等多因子檢測試劑盒(流式熒光法)(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) | 97-104 | 101 |
| EDTA plasma(n=5) | 95-104 | 99 |
| heparin plasma(n=5) | 89-105 | 98 |
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)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Salusin肽α(SALa)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) | 93-101% | 80-99% | 81-99% | 89-96% |
| EDTA plasma(n=5) | 80-101% | 82-93% | 90-99% | 81-92% |
| heparin plasma(n=5) | 80-99% | 82-101% | 78-90% | 82-99% |
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、向實驗板每孔內加入200μL分析緩沖液以預濕;
2、實驗前標準品、試劑及樣本準備;
3、加樣(標準品、樣本、磁珠、檢測溶液A),標準品或樣本50μL,加檢測溶液A 50μL,及磁珠10μL,25°C酶標板振蕩器孵育90分鐘;
4、磁吸甩干,加檢測溶液B 100μL,25°C振動孵育30分鐘;
5、磁吸洗板1次;
6、加鞘液100μL,旋渦震蕩10分鐘后讀數(shù)。
實驗原理
將Salusin肽α(SALa)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。在微孔中同時加入待測抗原(標準品或樣本)、生物素標記的抗原和微球。待測抗原與生物素標記抗原對特異性抗體進行競爭結合。加入PE標記的鏈霉親和素,上機讀數(shù)。MFI值(Median Fluorescence Intensity)和樣品中的Salusin肽α(SALa)等多因子檢測試劑盒(流式熒光法)濃度呈負相關。
