特异性

本试剂盒用于检测Ⅰ型胶原交联氨基端肽(NTXI)等多因子检测试剂盒(流式荧光发光法),经检测与其它相似物质无明显交叉反应。
由于受到技术及样本来源的限制,不可能完成对所有相关或相似物质交叉反应检测,因此本试剂盒有可能与未经检测的其它物质有交叉反应。

回收率

分别于定值血清及血浆样本中加入一定量的Ⅰ型胶原交联氨基端肽(NTXI)等多因子检测试剂盒(流式荧光发光法)(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)91-10197
EDTA plasma(n=5)97-105101
heparin plasma(n=5)79-10283
sodium citrate plasma(n=5)88-9692

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Ⅰ型胶原交联氨基端肽(NTXI)等多因子检测试剂盒(流式荧光发光法),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Ⅰ型胶原交联氨基端肽(NTXI)等多因子检测试剂盒(流式荧光发光法)含量的测定值与理论值的比率。

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、试剂及样本准备;
2. 加样(标准品、样本、磁珠、检测溶液A)标准品或样本50μL及磁珠10μL,加检测溶液A50μL,
    37°C酶标板振荡器孵育60分钟;
3. 磁吸洗板3次;
4. 加检测溶液B100μL,37°C振动孵育30分钟;
5. 磁吸洗板3次;
6. 加鞘液100μL,旋涡震荡2分钟后读数。

实验原理

将Ⅰ型胶原交联氨基端肽(NTXI)等多因子检测试剂盒(流式荧光发光法)抗体包被于磁珠,制成固相载体,向微孔中分别加入标准品或标本以及磁珠、标记VEGFA,标记的Ⅰ型胶原交联氨基端肽(NTXI)等多因子检测试剂盒(流式荧光发光法)和未标记的Ⅰ型胶原交联氨基端肽(NTXI)等多因子检测试剂盒(流式荧光发光法)与连接于固相载体上的抗体竞争结合,然后将未结合物洗净后,加入PE标记的亲和素,再次彻底洗涤后即可上机读数。MFI值和样品中的Ⅰ型胶原交联氨基端肽(NTXI)等多因子检测试剂盒(流式荧光发光法)呈负相关。
