白细胞介素 - 23(IL-23)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-23 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-12 家族其他成员交叉反应率<1%),适用于细胞培养上清、组织匀浆、巨噬细胞裂解液等样本。研究背景中,IL-23 作为 IL-12 家族异二聚体细胞因子,在 Th17 细胞分化及炎症维持中起核心作用,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,IL-23 通过结合 IL-23R/IL-12Rβ1 受体复合物,激活 JAK2-STAT3 通路促进 RORγt 表达,驱动 IL-17/IL-22 等细胞因子分泌,本试剂盒可捕捉其表达波动以解析相关调控网络。分子特征体现为 p19 亚基(特有功能域)与 p40 亚基(共享于 IL-12)形成异二聚体,亚基间相互作用为受体结合与信号激活提供结构基础;生物学意义在于作为 “Th17 细胞调控枢纽”,参与免疫平衡维持、黏膜屏障防御及组织修复模型中的炎症调控。实用性上,支持自身免疫模型中与 IL-17 的关联研究、JAK-STAT 通路解析及化合物对其分泌的干预评估,为免疫调控机制研究提供可靠工具。 |

| 靶点详情: | 白细胞介素 23(IL-23)是 IL-12 细胞因子家族成员,为异二聚体蛋白,主要由活化的树突状细胞、巨噬细胞及单核细胞分泌,通过调控辅助性 T 细胞亚群分化参与免疫应答调控。在科研模型中,IL-23 可诱导初始 T 细胞向 Th17 细胞分化并维持其存活,与自身免疫性炎症模型、组织纤维化模型的病理进程密切相关,是解析适应性免疫调控网络的关键分子靶点。属于异二聚体细胞因子,p19 亚基含 4 个 α 螺旋结构域(功能特异性区域),p40 亚基含细胞因子结构域及免疫球蛋白样折叠区;两亚基通过非共价键结合,p40 亚基负责与 IL-23R/IL-12Rβ1 受体复合物结合,p19 亚基介导信号特异性激活,此结构特征是其实现 Th17 细胞调控功能的分子基础。 |
