Figure 5.
SPECT imaging and post-SPECT biodistribution with radiolabeled PEG-HVGGSSV and PEG-control peptide in nude mice with heterotopic esophageal (OE33) tumors. The tumor on the right hind limb was irradiated with 3 doses of 3 Gy, and the left was sham control. Enhanced tumor binding of the PEG-HVGGSSV peptide is observed in OE33 tumors at both 48 h and 72 h post injection.****p<0.001.
