Methods for the production of helper-dependent adenoviral vectors

Helper-dependent adenoviral vectors (HDAd) are deleted of all viral coding sequences and have demonstrated tremendous potential for gene therapy by providing long-term, high-level transgene expression in the absence of chronic toxicity. Thus, HDAd are superior to early generation Ad for gene therapy of genetic diseases where long-term transgene expression is required. This chapter describes in detail the rescue, amplification, and large-scale production of HDAd.
