Fig. 2. Concentration of the 211At-labeled trastuzumab 10 in each organ of the A431 cell xenograft mouse model. A 150 μL 0.05% PBS-T solution containing 20 μg 10 labeled with 211At (0.60 MBq) was intravenously injected into the A431 xenograft mice (n = 4). The radioactivity of each organ was measured after dissection at 16 h (light blue bar), 24 h (orange bar), or 40 h (gray bar) post injection.
