Figure 4. Biodistributions of radioactivity (A) and tumor-to-normal organ ratios (B) of Ramos xenograft-bearing mice injected either with directly labeled ¹¹¹In-1F5 () or with 1F5-sAv followed 24 h later by CA and then 1 h later with ¹¹¹In-DOTA-biotin (). Data in A were obtained 24 h after injection of radioactivity and are shown as %ID/g ± SD. Data represent the mean of 3 mice in each group.
