Luciferase imaging after intravenous injection of unmodified and 5 kDa PEGylated Ad6-Luc 5 kDa PEGylated. Luciferase activity of nude mice treated with Ad6-Luc and Ad6-Luc 5 kDa PEG compared to the PBS control group at days 1, 4, 7, 14, 28, and 42 after treatment. Nude mice were implanted with 107 human DU145 prostate cancer cells subcutaneously in their right hind flank. When tumor volumes reached 200 mm3, groups of 9 or 10 mice were randomized and administered with a single intravenous dose of 3 × 1010 vp of the indicated viruses or with PBS. PBS, phosphate-buffered saline.
