腺相关病毒/AAV/和元生物/元载体/病毒包装

腺相关病毒（Adeno-associated virus，AAV）是一类无法自主复制、无包膜的二十面体微小病毒，其直径约20-26nm，含有4.7kb左右的线状单链DNA作为基因组。AAV感染约3周可达表达高峰

重组腺相关病毒载体（recombinant AAV, rAAV）是在非致病的野生型AAV基础上改造而成的基因载体，研究中采用的rAAV通常为AAV2型基因组与不同的衣壳蛋白结合产生的组合型重组腺相关病毒载体，即rAAV2/x，其中x为不同衣壳蛋白的血清型。

自互补AAV（Self-complementary AAV, scAAV）是在rAAV的基础上将其编码区域设计成双链DNA，感染细胞后互补部分互补形成双链DNA，不需等待第二链DNA合成，因此scAAV感染后3-5天即可到达表达峰值。
