An assessment of anti-EGFR affibody molecules ZEGFR:2377 labeled with gallium-68 via the commonly used DOTA (1,4,7,10-Tetraazacyclododecane-1,4,7,10-tetraacetic acid); chelator showed a high liver uptake (6.2 ± 0.3% ID/g) and relatively low tumor uptake (2.7 ± 0.1% ID/g) 3 h after injection [32]. This evidence concerns the gene EGFR and neoplasm.
