Fig. 7. The in vivo targeting assay of PPCRDF. (a) Mice were injected intravenously with PPCRD and PPCRDF, in vivo imaging was performed, and photographs were taken at 2 h and 24 h, and (b) their major organs at 12 h. (c) Mean fluorescence intensity (MFI) of the tumor tissues from mice at 1, 2, 8, 12, and 24 h post-injection, respectively.
