产品描述:CUSABIO试剂盒采用双抗体夹心法原理,专为定量检测人血清、尿液及脑脊液(CSF)中的唾液酸酶(Sialidase)水平而设计。唾液酸酶作为一类糖苷水解酶,广泛参与细胞表面糖蛋白和糖脂的代谢调控,其活性异常与微生物感染、神经炎症及神经退行性疾病的发生发展密切相关,例如细菌或病毒感染过程中病原体释放的唾液酸酶可促进组织侵袭,而阿尔茨海默病或帕金森病患者的脑脊液中可能检测到该酶的表达水平变化。试剂盒检测范围为0.312-20 ng/mL,最低检测灵敏度达0.312 ng/mL,适用于微量样本的高精度分析。操作流程基于预包被特异性捕获抗体的96孔板,通过生物素标记检测抗体与链霉亲和素-HRP显色系统实现目标蛋白的定量检测。该产品可应用于基础研究领域,如探究唾液酸酶在感染性疾病、神经系统疾病中的生物学功能,或评估其在体液中的动态变化规律,为疾病机制研究及生物标志物筛选提供可靠工具。试剂盒兼容血清、尿液及CSF等复杂体液样本,具备良好的稳定性和重复性,适用于实验室级科研分析需求。

功能:Catalyzes the removal of sialic acid (N-acetylneuraminic acid) moieties from glycoproteins and glycolipids. To be active, it is strictly dependent on its presence in the multienzyme complex. Appears to have a preference for alpha 2-3 and alpha 2-6 sialyl linkage.
