特異性

本試劑盒用于檢測調(diào)節(jié)激活正常T-細胞表達分泌因子(RANTES)，經(jīng)檢測與其它相似物質(zhì)無明顯交叉反應。
由于受到技術及樣本來源的限制，不可能完成對所有相關或相似物質(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調(diào)節(jié)激活正常T-細胞表達分泌因子(RANTES)（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) 82-98 92
EDTA plasma(n=5) 98-105 102
heparin plasma(n=5) 83-101 90

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)加入適量的調(diào)節(jié)激活正常T-細胞表達分泌因子(RANTES)，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調(diào)節(jié)激活正常T-細胞表達分泌因子(RANTES)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) 92-101% 79-101% 95-103% 80-90%
EDTA plasma(n=5) 78-92% 89-97% 92-105% 81-99%
heparin plasma(n=5) 84-98% 87-99% 91-104% 98-105%

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、試劑及樣本的準備；
2. 加樣（標準品及樣本）100µL，37°C孵育1小時；
3. 吸棄，加檢測溶液A100μL，37°C孵育1小時；
4. 洗板3次；
5. 加檢測溶液B100µL，37°C孵育30分鐘；
6. 洗板5次；
7. 加底物100µL，37°C孵育10分鐘；
8. 讀數(shù)。

實驗原理

將調(diào)節(jié)激活正常T-細胞表達分泌因子(RANTES)抗體包被于96孔微孔板中，制成固相載體，向微孔中分別加入標準品或標本，其中的調(diào)節(jié)激活正常T-細胞表達分泌因子(RANTES)與連接于固相載體上的抗體結合，然后加入生物素化的調(diào)節(jié)激活正常T-細胞表達分泌因子(RANTES)抗體，將未結合的生物素化抗體洗凈后，加入HRP標記的親和素，再次徹底洗滌后加入底物。加入底物后會產(chǎn)生輝光型光信號。發(fā)射光強度和樣品中的調(diào)節(jié)激活正常T-細胞表達分泌因子(RANTES)呈正相關。用化學發(fā)光儀測定相對光單位（RLU），計算樣品濃度。
