Figure 6.
SPECT imaging with radiolabeled PEG-HVGGSSV and PEG-control in nude mice with heterotopic lung (A549), pancreatic (BXPC3) and brain (D54) cancer. SPECT imaging (48 h post injection) in nude mice with heterotopic A549, BXPC3, D54 cancer. The tumor on the right hind limb was irradiated with 3 doses of 3 Gy. Enhanced tumor binding of the PEG-HVGGSSV peptide is observed in A549, BXPC3 and D54 tumors compared to the PEG-control.
