特異性
本試劑盒用于檢測血管活性腸肽(VIP)，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(duì)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血管活性腸肽(VIP)（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) | 81-96 | 88 |
| EDTA plasma(n=5) | 79-95 | 90 |
| heparin plasma(n=5) | 85-97 | 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(duì)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(duì)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)加入適量的血管活性腸肽(VIP)，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血管活性腸肽(VIP)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) | 96-103% | 88-102% | 91-105% | 78-104% |
| EDTA plasma(n=5) | 78-101% | 80-93% | 90-97% | 89-101% |
| heparin plasma(n=5) | 97-104% | 78-89% | 99-105% | 99-105% |
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(duì)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、試劑及樣本的準(zhǔn)備；
2. 加樣（標(biāo)準(zhǔn)品及樣本）50µL，
加入50µL檢測液A(臨用前配制);
37°C溫育1小時(shí)。
3. 洗板3次；
4. 加檢測溶液B100µL，37°C孵育30分鐘；
5. 洗板5次；
6. 加TMB底物90µL，37°C孵育10-20分鐘；
7. 加終止液50µL，立即450nm讀數(shù)。
實(shí)驗(yàn)原理
本試劑盒應(yīng)用競爭抑制酶聯(lián)免疫分析法測定標(biāo)本中待測物質(zhì)水平。將血管活性腸肽(VIP)單克隆抗體包被微孔板，制成固相載體，往包被抗體的微孔中同時(shí)加入生物素標(biāo)記的抗原和待測抗原(標(biāo)準(zhǔn)品或樣本)，待測抗原與生物素標(biāo)記抗原對(duì)特異性抗體進(jìn)行競爭結(jié)合。溫育后經(jīng)洗滌去掉未結(jié)合物，然后加入HRP標(biāo)記的親和素，經(jīng)過溫育和徹底洗滌后加入底物TMB顯色。TMB在過氧化物酶的催化下轉(zhuǎn)化成藍(lán)色，并在酸的作用下轉(zhuǎn)化成最終的黃色。待測標(biāo)本濃度越高，標(biāo)記抗原和抗體的結(jié)合就越受到抑制，顯色愈淺。顯色的深淺與酶量呈正相關(guān)，而與樣品中待測物質(zhì)含量呈負(fù)相關(guān)。用酶標(biāo)儀在450nm波長下測定吸光度（O.D.值），計(jì)算樣品濃度。
