scAAV-DJ Expression System

scAAV-DJ Expression System
  • Complete Expression System contains packaging plasmids, expression vector and GFP control vector
  • pHelper plasmid contains required E2A, E4, and VA RNA adenoviral genes; eliminates the need for a helper adenovirus
  • AAV-DJ system provides a hybrid capsid created from 8 different AAV serotypes to provide substantially higher infectivity rates across a broad range of tissues
  • Cloning capacity of expression vector = 1.5 kb


NOTE: AAV-DJ Helper Free Systems are available for sale to academic, government and non-profit research laboratories. All other purchasers require a commercial license for all fields including research use. Please contact our Business Development department for license information.

Product Details

The AAV Helper Free System produces recombinant AAV containing your gene of interest without the need to use a helper adenovirus. The adenoviral genes required for proper AAV packaging are provided in the pHelper plasmid (E2A, E4 and VA RNA) or in the 293 packaging cells (E1).

AAV Helper Free Complete Expression Systems are available for native serotypes 1 through 6, as well as the novel AAV-DJ and AAV-DJ/8. The AAV-DJ system provides a hybrid capsid created by DNA shuffling technology combining 8 different native serotypes: AAV-2, AAV-4, AAV-5, AAV-8, AAV-9, avian AAV, bovine AAV, and caprine AAV. The result is a highly infectious vector that can transduce a wide variety of cells and tissues at significantly higher rates than AAV-21.

Production and Transduction of Recombinant AAV. AAV2-GFP was produced by cotransfection of 293AAV cells (Catalog #AAV-100) with pAAV-GFP, pAAV-RC2, and pHelper plasmids. Upon harvesting viral supernatant, 293AD cells (Catalog #AD-100) were infected with AAV2-GFP for 48 hours.
