Genome-to-PFU ratios for chimeric Ad vectors^a

Virus	Genomes/ml (1012)	PFU/ml	Genome/PFU ratio
Ad5L	2.2	1.39 × 1011	13 ± 4.2
Ad5S	1.46	1.04 × 1010	140 ± 54
Ad5/9L	1.73	6.05 × 1010	29 ± 6
Ad5/9S	1.28	2.2 × 109	582 ± 158
Ad5/35L	1.6	1.16 × 1011	14 ± 4.8
Ad5/35S	1.98	1.18 × 1011	17 ± 6

^aThe genome titers of preparations of purified Ad vectors were measured by quantitative Southern blot analysis (61). The plaque titers were determined on 293 cells under the conditions described in Materials and Methods.
