  • M2-型丙酮酸激酶(PKM2)等多因子檢測試劑盒(流式熒光發(fā)光法) 產(chǎn)品包裝(模擬)
  • M2-型丙酮酸激酶(PKM2)等多因子檢測試劑盒(流式熒光發(fā)光法) 產(chǎn)品包裝(模擬)

特異性

本試劑盒用于檢測M2-型丙酮酸激酶(PKM2)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(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M2-型丙酮酸激酶(PKM2)等多因子檢測試劑盒(流式熒光發(fā)光法)(加標(biāo)樣品),重復(fù)測定并計(jì)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) 84-101 95
EDTA plasma(n=5) 90-97 94
heparin plasma(n=5) 79-90 83
sodium citrate plasma(n=5) 86-96 91

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(jì)算不同濃度樣本的平均值及SD值。
批間差:選取3個(gè)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(gè)樣本使用同一試劑盒重復(fù)測定8次,分別計(jì)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M2-型丙酮酸激酶(PKM2)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M2-型丙酮酸激酶(PKM2)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) 94-102% 98-105% 79-101% 97-105%
EDTA plasma(n=5) 78-102% 80-94% 93-101% 85-93%
heparin plasma(n=5) 86-101% 98-105% 89-97% 95-105%
sodium citrate plasma(n=5) 80-104% 97-105% 89-103% 83-96%

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(shí)驗(yàn)室的環(huán)境條件需盡量保持一致,尤其是實(shí)驗(yàn)室內(nèi)溫度、濕度及溫育條件。其次由同一實(shí)驗(yàn)員來進(jìn)行操作可減少人為誤差。

實(shí)驗(yàn)流程

1. 實(shí)驗(yàn)前標(biāo)準(zhǔn)品、試劑及樣本準(zhǔn)備;
2. 加樣(標(biāo)準(zhǔn)品、樣本、磁珠)標(biāo)準(zhǔn)品或樣本100μL及磁珠10μL,
    37°C酶標(biāo)板振蕩器孵育90分鐘;
3. 磁吸甩干,加檢測溶液A100μL,37°C酶標(biāo)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(dòng)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(shí)驗(yàn)原理

將M2-型丙酮酸激酶(PKM2)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(biāo)準(zhǔn)品或標(biāo)本以及磁珠,其中的M2-型丙酮酸激酶(PKM2)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(jié)合,然后加入生物素化的M2-型丙酮酸激酶(PKM2)等多因子檢測試劑盒(流式熒光發(fā)光法)抗體,將未結(jié)合的生物素化抗體洗凈后,加入PE標(biāo)記的親和素,再次徹底洗滌后即可上機(jī)讀數(shù)。MFI值和樣品中的M2-型丙酮酸激酶(PKM2)等多因子檢測試劑盒(流式熒光發(fā)光法)呈正相關(guān)。
