在该方案中,我们描述了使用 Amaxa Nucleofector 96 孔穿梭系统用 siRNA 有效转染小鼠巨噬细胞系的方法,用脂多糖刺激巨噬细胞,并监测对炎性细胞因子产生的影响。

该程序的总体目标是使用 RNA 干扰来研究候选基因对先天免疫反应的影响。在小鼠巨噬细胞中,为此,将小鼠巨噬细胞系胰蛋白酶化并与转染溶液和感兴趣的 SI RNA 混合,然后将混合物转移到 96 孔核 VETE 板中,并使用 Maxa 96 孔转染系统将 siRNA 转染到巨噬细胞中,并与细胞培养物孵育后, 将培养基、LPS 或其他先天免疫激活剂应用于转染的巨噬细胞以刺激它们。最后,进行 Eliza 检测以监测细胞因子的产生并评估 siRNA 处理对先天免疫反应的影响。

与脂质体介导的转染相比,该技术的主要优点是我们的检测方法稳健,可应用于高通量专业的许多基因。这种方法的关键是处理健康细胞,温和地处理它们,并在转染过程中高效工作。正如我们将要证明的,该方案使用原始的 2 64 0.7 小鼠巨噬细胞系,其按照随附文件中所述进行培养。
