Fig. 4From: Initial biological evaluations of 18F-KS1, a novel ascorbate derivative to image oxidative stress in cancerCell uptake of 18F-KS1 at baseline, promoter, and blockade conditions (n = 6) after 60 min in vitro in (a) SCC-61 and rSCC-61 and (b) in PC3 cell line under normoxic and hypoxic conditions after 60 min. The data were expressed as % injected dose (ID)/mg of protein present in each well, with **p ≤ 0.05 considered statistically significant. Plates without ligands are controlsBack to article page
