Construction, Production, and Purification of Recombinant Adenovirus Vectors

互联网

735
Recombinant adenoviruses provide a versatile system for gene expression studies and therapeutic applications. In this chapter, a standard procedure for their generation and small-scale production is described. Homologous recombination in E. coli between shuttle plasmids and full-length adenovirus backbones (E1-deleted) is used for the generation of recombinant adenoviral vectors genomes. The adenovirus genomes are then analyzed to confirm their identity and integrity, and further linearized and transfected to generate a recombinant adenoviral vector in permissive human cells. These vectors are then purified by two sequential CsCl gradient centrifugations and subjected to a chromatography step in order to eliminate the CsCl and exchange buffers. Finally, the viral stock is characterized through the quantification of its viral particle content and its infectivity.
