Figure 7 displays the tumor-to-organ ratios for 111In-IgG (Figure 7A) and 111In-Fab (Figure 7B). The tumor-to-organ ratios which exceeded the value of 1 were observed for the kidneys and heart for 111In-IgG and for the heart and liver for 111In-Fab, while the time–activity curves for 111In-IgG and 111In-Fab were quite similar to those in the MC38 model. This evidence concerns the gene FANCB and neoplasm.
