产品详情

  • 产品描述:
    本试剂盒(货号:CSB-E08345h)采用双抗体夹心酶联免疫吸附法,专为定量检测人血清、血浆及组织匀浆中胰岛素原(Proinsulin, PI)设计。胰岛素原是胰岛素生物合成的前体蛋白,主要由胰腺β细胞分泌,其水平变化可反映胰岛素分泌功能及β细胞活性,在糖尿病机制研究、代谢综合征评估及胰岛功能相关科研领域具有重要价值。试剂盒检测灵敏度高,线性范围为62.5-4000 pg/mL,最低检测限达31.2 pg/mL,包被板预封抗人PI单克隆抗体,通过生物素标记检测抗体与标准品/样本中的PI特异性结合,结合辣根过氧化物酶(HRP)标记链霉亲和素进行显色定量。适用于探索2型糖尿病发病机制、胰岛移植效果评估、胰岛素抵抗研究及药物干预对β细胞功能的影响等科研场景。实验全程需自备酶标仪、移液器等基础设备,提供预包被96孔板、标准品、检测抗体及全套反应试剂,开封后建议4℃保存并在1周内完成检测,确保结果准确性。

    Intra-assay Precision (Precision within an assay): CV%<8%

    Three samples of known concentration were tested twenty times on one plate to assess.

    Inter-assay Precision (Precision between assays): CV%<10%

    Three samples of known concentration were tested in twenty assays to assess.

  • 线性度:

    To assess the linearity of the assay, samples were spiked with high concentrations of human PI in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
