Human adenovirus (HAdV) is used extensively as a vector for gene delivery for a variety of purposes, including gene therapy and vaccine development. Most adenoviral vectors used for these approaches have a deletion of early region 1 (E1), which is complemented by the cell line. Most commonly, these are 293 cells for HAdV serotype 2 or 5. The 293 cells have the left end of HAdV5 integrated into chromosome 19 and express the E1 genes and protein IX. We observed that viruses with the E1 region deleted often grow less well o
