Fig. 3. Titration of Ad.HL.sr39TK for MicroPET/MicroCT quantification.
(Panel a) Two mice per group were injected intravenously with 1011, 3×1010, or 1010 IGU of Ad.HL.sr39TK or with 3×1010 IGU of Ad.HL.Luc2. After three days, mice were injected with 18F-FHBG (200 µCi) and subjected to microPET/microCT imaging. (Panel b) 2 mm ROIs were drawn within the liver of each mouse, and used to determine average %ID/g per liver. Data are means ± S.E.M.
