產品詳情

  • 產品描述：
    人妊娠特異性β1糖蛋白9(PSG9)酶聯免疫試劑盒（CSB-EL018859HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿樣本中的PSG9含量。人妊娠特異性β1糖蛋白9（PSG9）是一種由胎盤合體滋養層細胞合成的妊娠特異性糖蛋白，參與母胎界面免疫調節及胚胎發育。研究發現PSG9在子癇前期患者中表達下調，可能成為預測子癇前期的潛在生物標志物。試劑盒檢測范圍為5 μg/mL-150 μg/mL，適用于妊娠相關疾病的機制研究、胎盤功能評估及腫瘤生物學等科研領域；為生殖醫學、腫瘤微環境等基礎研究提供可靠工具本品僅用于科研，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。

  • 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%<15%        
    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 PSG9 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

  • 基因功能參考文獻：
    1. Results indicate that pregnancy-specific glycoprotein 9 (PSG9) may facilitate the development of hepatocellular carcinoma (HCC) by fostering angiogenesis via promoting VEGFA production in cancer HCC. PMID: 28078509
    2. Findings illustrate the innovative mechanism by which PSG9 drives the progression of colorectal cancer and tumor angiogenesis. This occurs via nuclear translocation of PSG9/SMAD4, which activates angiogenic cytokines. PMID: 27528036
    3. PSG9, through its activation of TGFbeta-1, could be a potent inducer of immune tolerance PMID: 27389696
    4. PSG9 may have a role in development of colorectal carcinogenesis in patients with adenomatous polyposis coli PMID: 15982419
