Tumor uptake was dependent on EGFR density, with the HT-29 xenograft having the highest expression with the highest tumor uptake and SW620 xenograft having the lowest: HT-29 (19.1 ± 1.4% IA/g) > DLD-1 (14.7 ± 0.3% IA/g) > MDA-MB-231 (12.8 ± 1.2% IA/g) > SW620 (4.4 ± 0.9% IA/g). Here, EGFR is linked to neoplasm.
