| 背景介绍 | 白细胞介素2(IL-2)是15kDa的糖蛋白，在人类中，由位于4号染色体q26–28区域的单基因编码。它是免疫系统中的一类信号分子，调控对具有免疫功能的白血球(白细胞，通常是淋巴细胞)的活性。IL-2是机体对微生物感染的天然应答，区别外来和自身抗原。IL-2通过与IL-2受体来发挥功能，其受体由3条链组成，分别为α链(CD25)、β链(CD122)和γ链(CD132)。
监测血清中的IL-2含量为多种病理状态提供更详细的视角，包括癌症、传染病、移植排斥、多发性硬化症、类风湿性关节炎、系统性红斑狼疮和I型糖尿病等。 |
| 检测原理 | 本试剂盒采用双抗体夹心酶联免疫吸附检测技术。特异性抗小鼠IL-2抗体预包被在高亲和力的酶标板上。酶标板孔中加入标准品、待测样本和生物素化的检测抗体，经过孵育，样本中存在的IL-2与固相抗体和检测抗体结合。洗涤去除未结合的物质后，加入辣根过氧化物酶标记的链霉亲和素(Streptavidin-HRP)。洗涤后，加入显色底物TMB，避光显色。颜色反应的深浅与样本中IL-2的浓度成正比。加入终止液终止反应，在450 nm波长(参考波长570 - 630 nm)测定吸光度值。 |
| 组分 | 包被抗 IL-2单克隆抗体的96孔聚苯乙烯酶标板 小鼠 IL-2 冻干标准品 IL-2检测抗体 标准品稀释液 辣根过氧化物酶标记的链霉亲和素 检测缓冲液(10×) 底物(TMB) 终止液 洗液(20×) |
