一 质粒简介：
1. 提供AAV包装必需的反式元件- AAV2的复制蛋白（Rep） 和7M8血清型的衣壳蛋白（Cap）。Rep蛋白负责病毒基因组的复制，Cap蛋白则组装成病毒外壳，决定了AAV的组织靶向性。
- 7M8是一种经过改造的AAV血清型，相比野生型，对视网膜细胞等组织具有更强的靶向能力，常用于眼部疾病的基因治疗研究。
2. 与其他质粒配合完成病毒包装
生产重组AAV通常需要三种质粒共同转染细胞：- 转移质粒（含ITR和目的基因）：携带需要被包装的治疗基因或报告基因。
- 辅助质粒（提供腺病毒辅助功能）：提供病毒复制所需的辅助因子。
- 质粒（7M8）：提供Rep和Cap蛋白，完成病毒的复制与包装。
