我们描述了一种方法来衡量 Fc 介导的效应函数的活化作用的抗体, 针对流感病毒血凝素。这种检测也可以适应评估单克隆抗体或多克隆血清靶向其他病毒表面糖蛋白, 以诱导 Fc 介导的免疫能力。

该方案的总体目标是评估抗体或血清样品激活 Fc 介导的效应子功能的能力。该方法可以通过测量抗体依赖性 Fc 介导的免疫的激活来帮助回答免疫学和疫苗学领域的关键问题。该技术的主要优点是,从材料制备到数据分析,实验可以在 24 小时内完成。

演示此程序的是 Peter Palese 实验室的研究生 Mark Bailey。为了通过转染诱导流感病毒血凝素表达,首先将人胚胎肾 293 细胞以每孔浓度的两倍 10 至第 4 个细胞浓度接种在白色组织培养物处理的 96 孔板中。在 37 °C、5% CO2 下放置 4 小时后,用每孔 100 ng 编码病毒血凝素的 DNA 和 0.2 μL 转染试剂以及总体积为 50 μL 的 1X 最佳还原血清培养基转染细胞。
