產(chǎn)品詳情

  • 產(chǎn)品描述:
    人糖類抗原19-9(CA19-9)酶聯(lián)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(guān)碳水化合物抗原,是臨床常用的腫瘤標(biāo)志物。其背景在于可作為胰腺癌、膽管癌等消化系統(tǒng)惡性腫瘤的輔助診斷指標(biāo)。研究機制方面,主要是檢測血清中CA19-9水平,當(dāng)患有相關(guān)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??捎糜谀[瘤機制探索、藥物療效評估或生物標(biāo)志物相關(guān)性分析等科研場景本品僅用于科研,不用于臨床診斷,產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。

  • 精密度:

    Intra-assay Precision (Precision within an assay): CV%<15%

         

    Three samples of known concentration were tested twenty times on one plate to assess.

     

    Inter-assay Precision (Precision between assays): CV%<20%

         

    Three samples of known concentration were tested in twenty assays to assess.

       
  • 線性度:

    To assess the linearity of the assay, samples were spiked with high concentrations of human CA19-9 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

靶點詳情

  • 最新研究進展:
    CA19-9是一種被廣泛用于胰腺癌診斷和監(jiān)測的糖蛋白。最近的研究表明,CA19-9可能有助于肝癌的診斷和治療。一項研究發(fā)現(xiàn),CA19-9陽性的肝癌患者具有較高的肝癌特異性死亡率,這表明CA19-9可能是一種對肝癌患者預(yù)后具有潛在價值的生物標(biāo)志物。此外,一些研究還發(fā)現(xiàn),CA19-9的水平可以在肝癌治療過程中用于評估治療反應(yīng)。
