In the final 24-hour imaging, ex vivo biodistribution confirmed that Glc(6)-Alb exhibited over twice the uptake in the tumor compared to Man-Alb (Glc(6)-Alb = 4.84 ± 0.67 %ID/g, Man-Alb = 2.38 ± 0.3 %ID/g), with evidence of intestinal excretion (Figure 5B and Table S23). This evidence concerns the gene ALB and neoplasm.
