Fig. 2From: Hybrid PET/optical imaging of integrin αVβ3 receptor expression using a 64Cu-labeled streptavidin/biotin-based dimeric RGD peptideSerum stability of the 64Cu-DOTA-(AF)SAv/biotin-PEG-RGD2. Stability was measured using PD-10 columns, and percent radioactivity was determined relative to the value at 0 h (100 %)Back to article page
