產品詳情

  • 產品描述:
    人綠膿桿菌外毒素A(PEA)酶聯免疫試劑盒(CSB-E11252h)為雙抗夾心法ELISA試劑盒,定量檢測血清、唾液、組織勻漿樣本中的PEA含量。PEA(Proximity Extension Assay,鄰位延伸分析技術)是一種結合抗體免疫分析和PCR或NGS技術的蛋白質組定量方法。其原理是利用特異性抗體與目標蛋白結合,通過DNA條形碼進行定量,具有高靈敏度和特異性,廣泛應用于臨床疾病研究和藥物研發。試劑盒檢測范圍為0.156 ng/mL-10 ng/mL,該產品可應用于基礎科研中感染模型建立、宿主 - 病原體互作研究、抗生素療效評估等場景,例如通過檢測不同感染階段生物樣本中的 PEA 濃度變化,揭示毒素釋放規律及其與疾病進展的關聯性,或用于篩選抑制 PEA 活性的潛在化合物。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%<8%      
    Three samples of known concentration were tested twenty times on one plate to assess.  
    Inter-assay Precision (Precision between assays): CV%<10%      
    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 PEA in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
