FIGURE 4.

Maximum-intensity PET projections acquired on day 14 for all animals. Overall, there is excellent consistency in whole-body activity and uptake in easily identifiable organs and tissues, and differences are noted across groups. Different gray scale is used for ⁸⁹Zr-DFO-squaramide–anti-gD group. Hot spots in the upper limb of some rhesus monkeys represent residual activity at injection site from day 0. Animal order (left to right) for each group is A, B, and C (Table 1).
