產(chǎn)品詳情

  • 產(chǎn)品描述：
    綿羊腫瘤壞死因子α(TNF-α)酶聯(lián)免疫試劑盒（CSB-E13853Sh）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的TNF含量。TNF（腫瘤壞死因子）是一種多功能促炎細胞因子，最初因能引起腫瘤組織壞死而得名。其超家族包括19個配體和29個受體，參與宿主防御、炎癥、細胞凋亡等生理過程。TNF通過與其受體結(jié)合，激活下游信號通路，調(diào)節(jié)細胞存活、凋亡和炎癥反應(yīng)。試劑盒檢測范圍為3.125 pg/mL-50 pg/mL，TNF-α的動態(tài)監(jiān)測對綿羊感染性疾病模型、疫苗研發(fā)及免疫機制研究具有重要價值；可高效支持動物醫(yī)學研究中炎癥相關(guān)疾病模型的建立、病原體感染后免疫應(yīng)答評估以及抗炎藥物作用機制的體外實驗，為畜牧科研中的免疫調(diào)控研究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。

靶點詳情

  • 功能：
    Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation. Induces insulin resistance in adipocytes via inhibition of insulin-induced IRS1 tyrosine phosphorylation and insulin-induced glucose uptake. Induces GKAP42 protein degradation in adipocytes which is partially responsible for TNF-induced insulin resistance. Plays a role in angiogenesis by inducing VEGF production synergistically with IL1B and IL6.; The TNF intracellular domain (ICD) form induces IL12 production in dendritic cells.
  • 基因功能參考文獻：
    1. The aim of the study was to assess the prognostic significance of Tumor Necrosis Factor-alpha, Interleukin-12(p40), Interleukin-6 and Interleukin 10 levels in cerebrospinal fluid (CSF) in sheep with encephalitic listeriosis. PMID: 25817420
    2. The p38 MAPK inhibitor decreased (P < 0.01) gene expression of TNFa but its effect was not observed at the level of TNFa protein synthesis PMID: 24995301
    3. TNF-alpha gene expression in multifidus was greater on both sides in the disc lesion animals than in the muscle of control animals. PMID: 24718080
    4. Injection of peptidoglycan-polysaccharide resulted in fever, increased concentrations of TNF-alpha on the day of and the day after challenge, and decreased concentrations of progesterone on days 14 and 21. PMID: 20603027
    5. These data are consistent with the effects of LPS on GH secretion originating through peripheral cytokine presentation to the pituitary, as well as a potential to act directly on selective populations of pituitary cells via CD14. PMID: 15899940
    6. plasma IL-1 beta, TNF-alpha and MCP-1 may potentially serve as markers to monitor prognosis of pregnancy toxaemia in ewes PMID: 17221363
