Serum stability of 99mTc-SER-4. 99mTc-SER-4 was incubated in the presence of phosphate-buffered saline (B) or serum (C) for 20 h at 37 °C then injected into SEC radioHPLC system. Percentage bound was assessed by comparison of bound activity (integral of 8 min and 25 s peak) to that of free activity (integral of 17 min and 45 s peak). 99mTcO4 is included as a control (A).
