產(chǎn)品詳情

  • 產(chǎn)品描述:
    人免疫球蛋白G4(IgG4)酶聯(lián)免疫試劑盒(CSB-E13728h)為競爭法ELISA試劑盒,定量檢測血清、血漿樣本中的IgG4含量。IgG4是一種免疫球蛋白,在免疫調(diào)節(jié)中發(fā)揮獨(dú)特作用。其背景上,IgG4異常與多種疾病相關(guān)。研究機(jī)制方面,它親和力成熟高,能發(fā)生Fab臂交換形成不對稱抗體,可阻斷抗原抗體相互作用,目前在自身免疫病、腫瘤等研究中受關(guān)注。試劑盒檢測范圍為39 ng/mL-10000 ng/mL,該產(chǎn)品適用于科研領(lǐng)域中對IgG4表達(dá)水平的體外研究,例如探索其在免疫調(diào)節(jié)、過敏反應(yīng)或纖維化疾病中的生物學(xué)作用,也可作為評估實(shí)驗(yàn)?zāi)P椭忻庖邞?yīng)答特征的輔助工具,為炎癥機(jī)制研究、生物標(biāo)志物篩選及藥物開發(fā)提供可靠數(shù)據(jù)支持本品僅用于科研,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%<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 IgG4 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
      Sample Serum(n=4)  
    1:1000 Average % 96  
    Range % 91-101  
    1:2000 Average % 99  
    Range % 93-104

    Range % 87-96  
    1:8000 Average % 90  
    Range % 85-94  
  • 回收率:
    The recovery of human IgG4 spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.
    Sample Type Average % Recovery Range  
    Serum (n=5) 84 80-88  
    EDTA plasma (n=4) 93 88-97
