Figure 4. Circulation and distribution of Gd-C5F12-PLNs in mice.

Figure 4

ICP-AES analysis of Gd in the blood after tail vein injection of the Gd-C5F12-PLNs showed that plasma half-life of Gd-C5F12-PLN-30 was 2.49±1.27 (A), Gd-C5F12-PLN-50 was 1.54±0.29 (B), and Gd-C5F12-PLN-100 was 1.58±0.17 (C). The body distribution of Gd-C5F12-PLNs was determined by [Gd] quantified by ICP-AES 24 hours after administering Gd-C5F12-PLNs in mice (D).
