產(chǎn)品詳情

  • 產(chǎn)品描述：
    兔子腫瘤壞死因子α(TNF-α)酶聯(lián)免疫試劑盒（CSB-E06998Rb）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿、細(xì)胞裂解物樣本中的TNF含量。TNF（腫瘤壞死因子）是一種重要的細(xì)胞因子，在免疫調(diào)節(jié)、炎癥反應(yīng)等生理病理過程中發(fā)揮關(guān)鍵作用。研究表明，TNF可激活多條信號通路，介導(dǎo)細(xì)胞存活、凋亡、炎癥因子釋放等。異常的TNF表達(dá)與多種疾病如類風(fēng)濕關(guān)節(jié)炎等密切相關(guān)，是藥物研發(fā)熱門靶點(diǎn)。試劑盒檢測范圍為78 pg/mL-5000 pg/mL，本試劑盒適用于兔模型在病原體感染、炎癥機(jī)制解析、藥物干預(yù)效果評估等基礎(chǔ)科研領(lǐng)域的研究需求，為探索TNF-α在免疫應(yīng)答中的動態(tài)變化提供可靠工具。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。

樣品類型：血漿（抗凝劑） EDTA

樣品信息：其他 兔

稀釋比：沒有稀釋

產(chǎn)品評價： 我用CSB-E06998Rb檢測模型組術(shù)前，術(shù)中30min-2h，術(shù)后24h血漿，四參數(shù)模型擬合出來的R2為0.99868（詳見圖片），標(biāo)準(zhǔn)曲線符合預(yù)期。0-2h的TNF-a水平符合升高趨勢，經(jīng)過文獻(xiàn)查詢，該模型需要6h才能檢測出大量升高的TNF-a炎癥因子水平，后續(xù)會測量6h及以上的炎癥因子水平。課題組師兄推薦，有兔子種屬，且價格實(shí)惠，測試結(jié)果準(zhǔn)確。

靶點(diǎn)詳情

  • 最新研究進(jìn)展：
    腫瘤壞死因子（TNF）是一種細(xì)胞因子，在免疫調(diào)節(jié)、炎癥和細(xì)胞凋亡等生物學(xué)過程中發(fā)揮重要作用。近年來的研究表明，TNF與各種疾病的發(fā)病機(jī)制有關(guān)，例如炎癥性疾病、腫瘤、自身免疫性疾病等。一些新的抗TNF治療藥物也被開發(fā)出來，已經(jīng)用于治療類風(fēng)濕性關(guān)節(jié)炎、克羅恩病等疾病，并獲得了一定的療效。
  • 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.

    1. TUNEL staining was positively correlated with TNF-a protein expression. Our findings suggest that apoptosis can be induced in the vocal fold epithelium after 120min of modal intensity phonation. In contrast, shorter durations of vibration exposure do not result in apoptosis signaling. PMID: 27577014
