血管紧张素1-7(Ang1-7)检测试剂盒(酶联免疫吸附试验法,小样本)

Mini Samples ELISA Kit for Angiotensin 1-7 (Ang1-7)

    特异性

    本试剂盒对检测血管紧张素1-7(Ang1-7)检测试剂盒(酶联免疫吸附试验法,小样本)具有较高的灵敏度。
    经检测人、小鼠、大鼠之间有100%的交叉反映。

    回收率

    分别于定值血清及血浆样本中加入一定量的血管紧张素1-7(Ang1-7)检测试剂盒(酶联免疫吸附试验法,小样本)(加标样品),重复测定并计算其均值,回收率为测定值与理论值的比率。

    样本回收率范围(%)平均回收率(%)
    serum(n=5)79-9789
    EDTA plasma(n=5)79-10582
    heparin plasma(n=5)78-9589

    精密度

    精密度用样品测定值的变异系数CV表示。CV(%) = SD/mean×100
    批内差:取同批次试剂盒对低、中、高值定值样本进行定量检测,每份样本连续测定20 次,分别计算不同浓度样本的平均值及SD值。
    批间差:选取3个不同批次的试剂盒分别对低、中、高值定值样本进行定量测定,每个样本使用同一试剂盒重复测定8次,分别计算不同浓度样本的平均值及SD值。
    批内差: CV<10%
    批间差: CV<12%

    线性

    在定值血清及血浆样本内加入适量的血管紧张素1-7(Ang1-7)检测试剂盒(酶联免疫吸附试验法,小样本),并倍比稀释成1:2,1:4,1:8,1:16的待测样本,线性范围即为稀释后样本中血管紧张素1-7(Ang1-7)检测试剂盒(酶联免疫吸附试验法,小样本)含量的测定值与理论值的比率。

    heparin plasma(n=5)92-101%94-101%87-104%78-104%

    稳定性

    经测定,试剂盒在有效期内按推荐温度保存,其活性降低率小于5%。
    为减小外部因素对试剂盒破坏前后检测值的影响,实验室的环境条件需尽量保持一致,尤其是实验室内温度、湿度及温育条件。其次由同一实验员来进行操作可减少人为误差。

    实验流程

    1. 实验前标准品、试剂及样本的准备;
    2. 加样(标准品及样本)25µL后,立即加入检测溶液A25µL,
        37°C孵育1小时;
    3. 甩干,洗板3次;
    4. 加检测溶液B50µL,37°C孵育30分钟;
    5. 洗板5次;
    6. 加TMB底物50µL,37°C孵育10-20分钟;
    7. 加终止液25µL,立即450nm读数。

    实验原理

    本试剂盒应用竞争抑制酶联免疫分析法测定标本中待测物质水平。将血管紧张素1-7(Ang1-7)检测试剂盒(酶联免疫吸附试验法,小样本)单克隆抗体包被微孔板,制成固相载体,往包被抗体的微孔中同时加入生物素标记的抗原和待测抗原(标准品或样本),待测抗原与生物素标记抗原对特异性抗体进行竞争结合。温育后经洗涤去掉未结合物,然后加入HRP标记的亲和素,经过温育和彻底洗涤后加入底物TMB显色。TMB在过氧化物酶的催化下转化成蓝色,并在酸的作用下转化成最终的黄色。待测标本浓度越高,标记抗原和抗体的结合就越受到抑制,显色愈浅。显色的深浅与酶量呈正相关,而与样品中待测物质含量呈负相关。用酶标仪在450nm波长下测定吸光度(O.D.值),计算样品浓度。
