产品详情

  • 产品描述:
    人糖类抗原19-9(CA19-9)酶联免疫试剂盒(CSB-E04773h)为双抗夹心法ELISA试剂盒,定量检测血清、血浆样本中的CA19-9含量。CA19-9是一种肿瘤相关碳水化合物抗原,是临床常用的肿瘤标志物。其背景在于可作为胰腺癌、胆管癌等消化系统恶性肿瘤的辅助诊断指标。研究机制方面,主要是检测血清中CA19-9水平,当患有相关癌症时其含量可能异常升高。试剂盒检测范围为10 U/mL-150 U/mL,灵敏度为3.8 U/mL。该产品适用于体外培养模型、动物实验或临床前研究中 CA19 - 9 表达水平的动态监测,可用于肿瘤机制探索、药物疗效评估或生物标志物相关性分析等科研场景本品仅用于科研,不用于临床诊断,产品具体参数及操作步骤详见产品说明书。

  • 最新研究进展:
    CA19-9是一种被广泛用于胰腺癌诊断和监测的糖蛋白。最近的研究表明,CA19-9可能有助于肝癌的诊断和治疗。一项研究发现,CA19-9阳性的肝癌患者具有较高的肝癌特异性死亡率,这表明CA19-9可能是一种对肝癌患者预后具有潜在价值的生物标志物。此外,一些研究还发现,CA19-9的水平可以在肝癌治疗过程中用于评估治疗反应。
