在本手稿中,描述了一种制备重组腺相关病毒 9 (rAAV9) 载体以纵小鼠心脏中基因表达的方法。

该程序的总体目标是制备重组腺相关病毒 9 或 rAAV9,以纵小鼠心脏中的基因表达。该方法可以回答心脏病学和分子遗传学领域的关键问题,例如如何在体内研究小鼠心脏的基因功能。这项技术的主要优点是,它将使我们能够轻松地在小鼠心脏体内纵基因表达和功能,从而允许基因功能获得功能,而不必依赖转基因动物模型。

生成 rAAV9 构建体并根据文本方案培养 HEK293 细胞后,为了在第 1 天转染细胞,将 70 μg AAV Rep-Cap 质粒、70 μg rAAV9 质粒和 200 μg Ad 辅助质粒混合在 50 mL离心管中。向试管中加入 49 毫升不含 FBS 的室温 DMEM 并充分混合。然后,要制备四比一的 PEI 到 DNA 溶液,向试管中加入 1, 360 微升 PEI 并充分混合。
