FIGURE 3. Biodistribution of cmAb U36-N-sucDf-⁸⁹Zr (hatched bars, n = 4) and cmAb U36-SMCC-SATA-Df-⁸⁹Zr (open bars, n = 4). Each conjugate (100 µg of mAb; 0.37 MBq) was injected into retroorbital plexus of HNX-OE–bearing nude mice. At 24 h (A), 48 h (B), and 72 h after injection (C), mice were bled, sacrificed, and dissected, and radioactivity levels (%ID/g ± SEM) of blood, tumor, organs, and gastrointestinal contents were assessed.
