Biodistribution and SPECT Imaging Study of 99mTc Labeling NGR Peptide in Nude Mice Bearing Human HepG2 Hepatoma
Figure 2
Stability of -NGR peptide in PBS (pH = 7.4) and mouse serum at 37°C for 1, 3, 6, and 12 h. Its radiochemical purity was >98%. 92% of -NGR peptide almost remained intact in PBS and mouse serum after 12 h of incubation.
