產(chǎn)品詳情

  • 產(chǎn)品描述：
    人補(bǔ)體成分C8β鏈(C8B)酶聯(lián)免疫試劑盒（CSB-EL004195HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的C8B含量。人補(bǔ)體成分C8β鏈（C8B）是補(bǔ)體系統(tǒng)的一部分，參與免疫反應(yīng)和炎癥過程。其研究機(jī)制涉及C8β鏈與C5b67結(jié)合，激活C8αγ，進(jìn)而參與膜攻擊復(fù)合物的形成，對病原體進(jìn)行殺傷。試劑盒檢測范圍為2.74 pg/mL-2000 pg/mL，其標(biāo)準(zhǔn)化操作流程支持科研人員探究補(bǔ)體系統(tǒng)在感染、炎癥或自身免疫性疾病中的作用機(jī)制，例如通過分析不同病理?xiàng)l件下血清或組織中C8β鏈的表達(dá)差異，揭示補(bǔ)體激活途徑的調(diào)控規(guī)律。此外，還可用于評估藥物干預(yù)或基因編輯模型對補(bǔ)體相關(guān)通路的影響，為免疫學(xué)基礎(chǔ)研究及轉(zhuǎn)化醫(yī)學(xué)提供可靠工具。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。

    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 C8B in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

靶點(diǎn)詳情

  • 功能：
    Constituent of the membrane attack complex (MAC) that plays a key role in the innate and adaptive immune response by forming pores in the plasma membrane of target cells.
  • 基因功能參考文獻(xiàn)：
    1. The binding specificity between C8 beta and C8 alpha subunits is determined by a cooperative interaction of the N-terminal thrombospondin type 1 module and the membrane attack complex/perforin domain. PMID: 12220191
    2. results indicate that the principal binding site for C9 lies within the MACPF domain of C8alpha; they also suggest this site and the binding sites for C8beta and C8gamma are distinct PMID: 16618117
