产品描述：
人糖类抗原19-9(CA19-9)酶联免疫试剂盒为双抗夹心法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。
