In addition, when NTR1 was labeled with imaging probes synthesized from 64 Cu-AmBaSar-NT and IRDye800-NT in vivo (55), in-vivo imaging showed higher uptake in 64 Cu-AmBaSar-NT tumors; one h and four h post-injection ID/g were 3.76 ± 1.45 and 2.29 ± 0.10%, respectively; fluorescence imaging of IRDye800-NT showed good, tumor contrast. This evidence concerns the gene NTSR1 and neoplasm.
