 常见问题解答
Q:

我想知道正常大鼠的正常血清TNFa浓度,以及实验大鼠诱导游离佐剂RA的血清TNFa浓度,以ng/ml为单位。另外我还想问一下,实验动物在诱导弗氏佐剂关节炎RA期间7周内的体重损失,以g为单位。

A:
我们使用CSB-E11987r大鼠TNF-α ELISA试剂盒来测量正常大鼠血清/血浆样本。具有严重炎症的模型甚至可以达到数百pg/ml的水平。结果会因样品不同条件和不同生物模型而异。至于您上述提到的诱导模型,我们对样品条件不太确定。具体以客户实测为准。 至于您关于体重损失的问题,通常取决于您自己的实验目的或目标的选择。如果您只想测试TNF-α,那么仅使用TNF-α elisa kit检测就可以了。

  • 最新研究进展:
    TNF(肿瘤坏死因子)是一种重要的细胞因子,在炎症反应、免疫调节、细胞凋亡等方面具有重要作用。最近的研究表明,TNF参与了多种疾病的发生发展,如类风湿关节炎、炎症性肠病、心血管疾病等。研究还表明,TNF对肿瘤的抑制和促进作用也是不可忽视的。
  • 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.
