腺相关病毒( adeno-associated virus,AAV) 是一类细小病毒,基因组为单链DNA,对分裂细胞和非分裂细胞均具有感染能力。通常需要腺病毒或疱疹病毒帮助其在体内复制扩增。重组腺相关病毒(recombinant AAV, rAAV)是利用AAV2 型基因组与不同血清型的衣壳蛋白基因组结合产生的混合体病毒载体,可将目的基因的CDS 区序列或者RNAi 干扰序列插入rAAV 表达质粒中,包装病毒后感染细胞完成对目的基因的操作。腺相关病毒具有感染温和,免疫原性小,长效稳定表达的特点,主要应用于动物体内注射。源井生物提供的腺相关病毒颗粒经过超速离心纯化,并通过qPCR对病毒基因拷贝进行滴定。腺相关病毒的滴度在10^12~10^13GC/ml,可以满足各类整体实验的使用要求。
