In the adenovirus library, 21bp of random oligonucleotides were inserted between Csp45I and SpeI sites in the HI-loop of fiber coding region. In AdDCAR-SYE and AdDCAR-IVR, oligonucleotides (TCGTATGAGAATTTTAGTGCG: SYENFSA, ATTGTTCGTGGTCGGGTGTTT: IVRGRVF) were inserted, respectively.

PC3 or AsPC-1 cells were infected with AdDCAR, AdDCAR-SYE and Ad-EGFP at MOI of 30. Cells were harvested at each day and genomic DNA was extracted for quantitative PCR analysis of fiber knob and cellular GAPDH (730 Real Time PCR System: Applied Biosystems, Foster City, CA). The amount of capsid DNA in each sample was normalized to GAPDH at each time point, and compared with adenovirus DNA at day 3.
