产品详情

  • 产品描述:
    CUSABIO试剂盒采用竞争酶联免疫法(ELISA)定量检测人、犬血清、尿液及组织匀浆样本中的犬尿氨酸(KYN)。KYN是色氨酸代谢通路中的关键代谢产物,参与调节免疫应答和神经递质平衡,其浓度异常与神经退行性疾病(如阿尔茨海默病)、抑郁症及免疫系统疾病的研究密切相关。本试剂盒检测范围为7.8-500 pmol/mL,通过预包被特异性抗体的微孔板实现精准检测,样本中的KYN与标记抗原竞争结合抗体,显色强度与KYN浓度呈负相关,配合标准曲线完成定量分析。产品适用于科研场景中KYN代谢机制研究、疾病模型评估及药物开发过程中的生物标志物检测,例如探索神经系统疾病动物模型的代谢变化或免疫调节药物对色氨酸代谢通路的影响。试剂盒包含实验所需预包被板、标准品、检测抗体及显色底物,操作流程优化至3.5小时内完成,兼容常规实验室设备,为多类型生物样本的KYN水平分析提供稳定可靠的检测方案。

    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 KYN in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
