This table contains a general list of plasmids that are useful in the production of AAV. Many of these plasmids encode the AAV genome (i.e., the genetic information that will be contained in the virion) and/or can be used to generate infectious AAV particles. Additional helper plasmids (which may not be available at Addgene) may be required to produce infectious AAV particles. You can search or sort this table based on plasmid name, species, gene name, and more
Addgene is a nonprofit plasmid repository. We store and distribute high-quality plasmids from your colleagues In addition to Rep and Cap, AAV requires a helper plasmid containing genes from adenovirus. These genes (E4, E2a and VA) mediate AAV replication. The transfer plasmid, Rep/Cap, and the helper plasmid are transfected into HEK293 cells, which contain the adenovirus gene E1+, to produce infectious AAV particles. Rep/Cap and the adenovirus helper genes may also be combined into a single plasmid; the separation of Rep and Cap shown in the figure on the right facilitates the viral pseudotyping. AAV preparations are generated in HEK293 cells either in-house by Addgene scientists or through collaboration with viral vector manufacturing facilities. Transfections are performed using the transfer plasmid, a plasmid encoding rep and serotype-specific cap, and a plasmid encoding adenoviral helper sequences
Check out the Addgene AAV Production protocol for more details. Pro tips. I'm not going to lie, AAV transfer plasmids are kind of a pain to work with. These plasmids contain ITRs which are required for proper packaging of AAV, but also form secondary structures that are prone to deletion from the transfer plasmid. The good news is there's a. The AAVpro Packaging Plasmids are sets of two plasmids (pRC and pHelper) designed to generate high-titer adeno-associated virus (AAV). AAV particles are generated without the use of a helper virus: simply cotransfect these plasmids and an AAV vector containing your gene of interest into the AAVpro 293T Cell Line (sold separately), and harvest high-titer AAV AAV-2 Rep-Cap Plasmid Use this AAV Rep-Cap plasmid along with the AAV Helper Free System to produce recombinant human adeno associated virus (rAAV) virions without the need for a helper virus Ideal if you already have the AAV Helper Free System with a different AAV serotype Frequently Asked Questions about AAV Expression and Packagin
and the transfer plasmid which contains the viral genome. In today's blog post, we'll focus on the packaging plasmid and take a look at each of its parts. Key elements of the AAV packaging plasmid. The packaging plasmid aka the RepCap plasmid encodes two genes: the replication (rep) gene and the capsid (cap) gene Packaging an infective recombinant adeno-associated virus (AAV) requires the presence of certain adenoviral gene products. The AAV Helper Free System eliminates the need for a helper adenovirus, making the system safer and more convenient. Most of the required adenoviral gene products (E2A, E4, and VA RNA) are present in a pHelper plasmid; the E1 adenovirus gene is supplied by the 293 host. As of 2014 Addgene's repository comprised 30,000 plasmids, deposited by 1,700 labs. Its plasmid collection contains plasmids used for functions such as genome engineering (including CRISPRS), gene expression, shRNA knockdown, viral-mediated gene delivery, detection of miRNA and promoter activity. The plasmid collection includes Use one of these control plasmids to construct a recombinant control adeno-associated virus by co-transfection with an AAV Packaging System. Each construct is provided as 10 µg of purified plasmid DNA Addgene also provides ready-to-use AAV and lentiviral preparations of commonly requested plasmids as a service to scientists. Addgene offers free online educational resources and protocols about..
For transgene plasmids, we sequence to verify that no mutational changes have occurred in any DNA that will be packaged into the AAV capsid. For AAV capsid plasmids, the presence of the correct cap gene is verified by full-length sequencing. SDS-PAGE purity- $138 Penn Vector Core strives to make the purest vector possible Since AAV titers tend to be in the range of 10 12 to 10 13 GC/mL, you must serially dilute your virus before adding your sample to a mastermix. At Addgene, we typically load 3 dilutions onto our ddPCR plate. As the titer is unknown, each dilution should fall within the range of the assay for a wide range of titers. We usually dilute our samples 1:6 million to 1:25 million
Here is an overview of our different AAV plasmid vectors and existing viruses (ready-made). You can enter the corresponding catalog number in our order system and have your desired virus produced. External users must complete an MTA between the Charité and its facility, and for some vectors, appropriate Addgene regulations must be applied Our AAV Rep-Cap plasmids work with our AAV Helper Free Systems to produce recombinant AAV more safely and easily, without the need for a helper virus. Choose one of these plasmids if you already have the AAV Helper Free System and would like to try a different AAV serotype. Recent Product Citations . Chen, S.H. et al. (2020). A Simple, Two-Step, Small-Scale Purification of Recombinant Adeno. Viele der für diese Zwecke eingesetzten Plasmide sind kommerziell erhältlich, sie werden aber auch zwischen Laboren geteilt und sind häufig bei nicht-kommerziellen Anbietern, wie Addgene, erhältlich.Sie leiten sich von den natürlich vorkommenden Plasmiden ab und besitzen noch deren strukturelle Bestandteile wie den Replikationsursprung (Origin of Replication, ORI) In addition to Rep and Cap, AAV requires a helper plasmid containing genes from adenovirus. These genes (E4, E2a and VA) mediate AAV replication.

Addgene's AAV are made from plasmids that are currently in our repository. You can obtain the plasmid from us or receive a ready-to-use viral preparation from the inventory below. AAV are distributed as 100 µL solutions of purified viral particles that are suitable for in vivo use
