Figure 4:
In vitro properties of 89Zr-TiO2-Tf: (A) cell-free ROS production 24 h, 48 h, and 72 h after treatment with the indicated compounds; (B) MM1.S cell viability in response to different amounts of 89Zr activity after treatment for 72 h; (C) ROS production by MM1.S cells 72 h after treatment with 89Zr-TiO2-Tf, 89Zr, and TiO2 compared to the untreated cells; (D) MM1.S cell viability 72 h after treatment with indicated compounds; (E) active caspase-3 levels in MM1.S cells 72 h after being treated with the indicated compounds. 89Zr is used as 89Zr-oxalate.
