产品概述
细胞白介素2(IL-2)是一种主要由有丝分裂中具有抗原活性的T淋巴细胞产生的多效应细胞因子。它在促进抗原特异性T细胞克隆中发挥着重要的作用。另外,已被证明白细胞介素2(IL-2)可以调解各种类型细胞的多种免疫应答。白细胞介素2(IL-2)刺激胸腺细胞增殖,刺激增殖和分化活化的B细胞,促进生长、分化和灭活单核细胞,诱导细胞因子的生产和增长,诱导普通杀伤细胞增加细胞溶解活动,提高淋巴细胞激活的杀伤(LAK细胞)细胞,诱导增殖和分化少突胶质细胞。大鼠白细胞介素2(IL-2)cDNA为含有155个氨基酸残基的前体糖蛋白、包含20个氨基酸残基信号肽,粘合形成成熟蛋白。在氨基酸序列水平,成熟的大鼠白细胞介素2(IL-2)与小鼠白细胞介素2(IL-2)的同源性达80%。
产品原理
本实验采用双抗体夹心ELISA法。抗大鼠IL-2单抗包被于酶标板上,同时加入标本、标准品和生物素化的抗大鼠IL-2抗体,标本、标准品中的IL-2会与加入于孔中的生物素化的抗大鼠IL-2抗体及包被于酶标板上的单抗结合,形成免疫复合物,游离的成分被洗去;加入辣根过氧化物酶标记的亲合素,亲合素与生物素特异性结合,游离的成分被洗去。加入显色底物(显色剂),若反应孔中有IL-2,辣根过氧化物酶会使无色的显色剂变蓝,加终止液变黄。在450nm处测OD值,IL-2浓度与OD450值之间呈正相关,可通过绘制标准曲线求出标本中IL-2浓度。
