產(chǎn)品詳情

  • 產(chǎn)品描述:
    大鼠白介素21(IL-21)酶聯(lián)免疫試劑盒(CSB-E11843r)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IL21含量。IL21,即白細(xì)胞介素-21,是一種由CD4+T細(xì)胞和自然殺傷T(NKT)細(xì)胞產(chǎn)生的細(xì)胞因子,屬于IL-15/IL-21家族。它通過(guò)結(jié)合IL-21R受體激活JAK1和JAK3信號(hào),進(jìn)而調(diào)節(jié)T、B、NK細(xì)胞和DC的增殖與分化,在免疫調(diào)節(jié)中發(fā)揮重要作用。IL21在多種免疫疾病中扮演關(guān)鍵角色,如自身免疫性疾病和癌癥。試劑盒檢測(cè)范圍為15.6 pg/mL-1000 pg/mL,適用于體外定量分析大鼠外周血或組織樣本中IL-21的動(dòng)態(tài)變化,可廣泛應(yīng)用于免疫調(diào)節(jié)機(jī)制研究、炎癥性疾病動(dòng)物模型評(píng)估或藥物干預(yù)后免疫指標(biāo)變化的科研分析本品僅用于科研,不用于臨床診斷,產(chǎn)品具體參數(shù)及操作步驟詳見(jiàn)產(chǎn)品說(shuō)明書(shū)。

靶點(diǎn)詳情

  • 功能:
    Cytokine with immunoregulatory activity. May promote the transition between innate and adaptive immunity. Induces the production of IgG(1) and IgG(3) in B-cells. Implicated in the generation and maintenance of T follicular helper (Tfh) cells and the formation of germinal-centers. Together with IL6, control the early generation of Tfh cells and are critical for an effective antibody response to acute viral infection. May play a role in proliferation and maturation of natural killer (NK) cells in synergy with IL15. May regulate proliferation of mature B- and T-cells in response to activating stimuli. In synergy with IL15 and IL18 stimulates interferon gamma production in T-cells and NK cells. During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation.
  • 亞細(xì)胞定位:
    Secreted.
  • 蛋白家族:
    IL-15/IL-21 family
