AAV Packaging Technical Detail
Adeno-associated virus (AAV) is a kind of Parvovirus, which genome is single-stranded DNA. It can infect both divisive and non-divisive cells. Adenoviruses or herpes viruses are usually needed to assist AVV to replicate in vivo. Recombinant AAV (rAAV) is a viral vector that combines the AAV2 genome with capsid protein genomes of different serotypes. CDS or RNAi interference sequences of the target genes can be inserted into the rAAV plasmid. AAV is mainly used in vivo injection because it has low immunogenicity and long-term expression.
Ubigene's AAV will be purified by ultracentrifugation, and its genome copy will be titrated by qPCR. The titer of AAV ranged from 10^12 to 10^13 v. g. / ml.
Different serotypes of AAVs have different transduction efficiency for tissues and cells. There are 10 different AAV serotypes in our packaging service. It is highly recommended that customers should select the corresponding AAV serotypes for different tissues:
AAV1 SM,CNS,lung,retina,pancreas,heart,liver
AAV2 SM,SNS,liver,kidney,retina
AAV4 CNS,retina,lung,kidney
AAV5 SM,CNS,lung,retina
AAV6 SM,heart,lung,adipose,liver
AAV7 SM,retina,CNS,liver
AAV8 SM,CNS,retina,liver,pancreas,heart,kidney,adipose
AAV9 SM,lung,liver,heart,pancreas,CNS,retina,testes,kidney
AAVrh10 SM,lung,liver,heart,pancreas,CNS,retina,kidney
AAVDJ/8 SM, liver, CNS, retina
AAVPHP.eB CNS(stronger than AAVPHP.B)

Ultra-purified large size 1*10^13 GC 2-3weeks In vivo injection
Work Flow and Validation:
Knockout AAV
The gene knockout AAV vector would be constructed and packaged as AAV. After ultracentrifugation purification, it can be used for in vivo injection. Cells infected with AAV can stably express gRNA and Cas9 protein to knockout the target gene.
Gene knockout of AAV vector selection
YKO seriesVectorReporter gene; Selection marker
YKO-AAV002-gRNA mCherry
Due to the limited capacity of AAV, SaCas9 protein can be used. SaCas9 and gRNA on the same construct can increase transduction efficiency.
Expression AAV
The gene overexpression vector would be constructed and packaged as AAV. After ultracentrifugation purification, it can be used for in vivo injection.
YOE seriesVectorReporter gene; Selection marker
YOE-AAV002 mCherry
Customers can choose a variety of tissue-specific promoters that can achieve tissue-specific expression in vivo,Click to showshouzhi
