白细胞介素 1 受体 2蛋白(IL-1R2)酶联免疫吸附试验试剂盒
| 产品描述: | 本试剂盒采用双抗夹心法 ELISA 技术,专为科研场景设计,可定量检测样本中 IL-1R2 蛋白浓度,检测范围为 10-1000pg/mL,包含预包被特异性捕获抗体的微孔板、HRP 标记检测抗体及配套试剂,特异性强(与 IL-1 受体家族其他成员交叉反应率<1%),适用于细胞裂解液、组织匀浆、细胞培养上清等样本。研究背景中,IL-1R2 作为 IL-1 受体家族的诱饵受体,在先天免疫与炎症信号调控中起核心作用,其表达异常与自身免疫模型、慢性炎症模型的病理进程相关;机制上,其胞外域通过特异性结合 IL-1α/IL-1β,阻断配体与功能性受体 IL-1R1 的相互作用,从而负调控 NF-κB 通路及促炎因子释放,本试剂盒可捕捉其表达波动以解析炎症信号的精细调控网络。分子特征体现为含胞外三个 Ig 样结构域(负责配体结合)、跨膜区及短胞内域(缺乏信号传导基序),结构域协同实现 “配体隔离” 功能;生物学意义在于作为 “炎症信号缓冲器”,参与免疫稳态维持(如限制过度炎症损伤)、胚胎发育中的炎症微环境调控及肿瘤微环境的免疫抑制平衡。实用性上,支持炎症模型中与 IL-1 家族细胞因子的关联研究、NF-κB 通路负调控机制解析及化合物对其表达的干预评估,为免疫调控机制研究提供可靠工具。 |

| 靶点详情: | IL-1R2(白细胞介素 1 受体 2)是 IL-1 受体家族的关键成员,作为诱饵受体在炎症信号通路中发挥负调控作用。属于 I 型跨膜蛋白,胞外区含三个 Ig 样结构域(配体结合核心区域),跨膜区连接胞内域;胞内域缺乏 TIR(Toll/IL-1 受体)结构域,无法启动信号传导,此结构特征使其成为功能性 IL-1 信号的天然拮抗剂,是其实现诱饵受体功能的分子基础。其通过竞争性结合 IL-1α、IL-1β 等配体,阻止配体与功能性受体结合,从而抑制下游炎症信号激活,在维持免疫平衡中起重要作用。在科研模型中,IL-1R2 的异常表达与自身免疫性疾病模型的炎症失衡、肿瘤微环境的免疫抑制状态密切相关,是解析炎症调控网络的重要分子靶点。 |
