  • 產(chǎn)品描述：
    大鼠白介素33(IL-33)酶聯(lián)免疫試劑盒（CSB-E14077r）為雙抗夾心法ELISA試劑盒，定量檢測(cè)血清、血漿、組織勻漿樣本中的IL33含量。IL-33是一種前炎癥細(xì)胞因子，屬于IL-1家族，主要在細(xì)胞損傷時(shí)釋放，誘導(dǎo)Th2型炎癥反應(yīng)。其與ST2受體結(jié)合后，激活下游信號(hào)通路，調(diào)節(jié)多種免疫細(xì)胞功能。IL-33在腫瘤、自身免疫疾病和過敏性疾病中發(fā)揮重要作用。試劑盒檢測(cè)范圍為15.6 pg/mL-1000 pg/mL，適用于基礎(chǔ)科研中炎癥機(jī)制研究、免疫調(diào)控模型分析以及藥物干預(yù)效果評(píng)估等方向，例如在呼吸道炎癥模型、自身免疫疾病或創(chuàng)傷修復(fù)實(shí)驗(yàn)中定量分析IL - 33的動(dòng)態(tài)變化。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(diǎn)詳情

  • 功能：
    Cytokine that binds to and signals through the IL1RL1/ST2 receptor which in turn activates NF-kappa-B and MAPK signaling pathways in target cells. Involved in the maturation of Th2 cells inducing the secretion of T-helper type 2-associated cytokines. Also involved in activation of mast cells, basophils, eosinophils and natural killer cells. Acts as a chemoattractant for Th2 cells, and may function as an 'alarmin', that amplifies immune responses during tissue injury.; In quiescent endothelia the uncleaved form is constitutively and abundantly expressed, and acts as a chromatin-associated nuclear factor with transcriptional repressor properties, it may sequester nuclear NF-kappaB/RELA, lowering expression of its targets. This form is rapidely lost upon angiogenic or proinflammatory activation.
