AAV Helper Free Packaging Systems

AAV Helper Free Packaging Systems

Cambridge Bioscience offers adeno-associated virus (AAV) helper-free packaging systems for the efficient packaging of your recombinant adeno-associated virus with your own expression vector without the use of a helper virus. Eliciting very mild immune responses in animal models, the AAV helper-free packaging systems are available for native serotypes 1 through to 6, as well as AAV-DJ and AAV-DJ/8.

AAV Helper-Free System
Most of the adenovirus gene products required for the production of infective AAV particles are supplied on the pHelper plasmid (i.e. E2A, E4, and VA RNA genes) that is co-transfected into cells with human AAV vector DNA. The remaining adenoviral gene product is supplied by the 293 host cells, which stably expresses the adenovirus E1 gene. By eliminating the need for live helper virus, the AAV helper-free system provides a safer and more convenient gene delivery system.

Viral Gene Delivery using the AAV Helper Free System

Available AAV Helper-Free Systems
We offer a range of AAV helper free packaging systems
1. AAV native serotypes 1 - 6
2. AAV-DJ - Engineered by DNA family shuffling to create a hybrid capsid from 8 different native serotypes. AAV-DJ vectors convey significantly higher infectivity rates compared to native serotypes across a broad range of tissues

3. AAV-DJ/8 - AAV-DJ/8 is a mutant of AAV-DJ, which is similar to native serotypes 8 and 9 in its ability to infect heart & brain tissue

AAV Expression Vectors
We offer a range of AAV expression vectors. These vectors are designed to work with any AAV packaging system including our AAV helper-free packaging systems. Find out more Here
