Quantification of imaging data showed that the tumor uptakes of 64Cu-αCD11b in the untreated, Abraxane-treated, and αCSF-1 plus Abraxane-treated mice were 2.67 ± 0.15, 4.07 ± 1.10, and 3.23 ± 0.32 %ID/g, respectively, 24 h after injection (Figure 4B). This evidence concerns the gene AACS and neoplasm.
