                                            產品描述:人糖類抗原19-9(CA19-9)酶聯免疫試劑盒(CSB-E04773h)為雙抗夾心法ELISA試劑盒,定量檢測血清、血漿樣本中的CA19-9含量。CA19-9是一種腫瘤相關碳水化合物抗原,是臨床常用的腫瘤標志物。其背景在于可作為胰腺癌、膽管癌等消化系統惡性腫瘤的輔助診斷指標。研究機制方面,主要是檢測血清中CA19-9水平,當患有相關癌癥時其含量可能異常升高。試劑盒檢測范圍為10 U/mL-150 U/mL,靈敏度為3.8 U/mL。可用于腫瘤機制探索、藥物療效評估或生物標志物相關性分析等科研場景本品僅用于科研,不用于臨床診斷,產品具體參數及操作步驟詳見產品說明書。
