Ex vivo biodistribution profile of radiolabelled 4hD29 and control nanobodies in mice implanted with a Kelly neuroblastoma subcutaneous tumour or intramuscular EndoC-βH1 transplants. Ex vivo biodistribution analysis of radiolabelled 4hD29 or control (non-specific) nanobody (BcII10) was performed in mice xenografted with Kelly neuroblastoma cells (n = 4) (A,CE) or with EndoC-βH1 transplants (n = 5) (B,FH). The evaluation was done 60 or 80 minutes, respectively, after i.v. administration of 5 µg 99mTc-labelled nanobody 4hD29 (white bars) or control nanobody BcII10 (black bars) and expressed as percent of injected activity per gram of tissue (%IA/g) ± SEM; (C,F) Individual uptake levels of tracers in Kelly tumours (C) or EndoC-βH1 transplants (F). Tumour-to-blood (D,G) and tumour-to-muscle ratios (E,H) of individual mice with either Kelly tumours (D,E) or EndoC-βH1 transplants (G,H). Data is presented as mean ± SEM; unpaired t-test, *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001.
