Quantitative ex vivo tissue counting biodistribution data for [99mTc]GVs and [99mTc]Tz (3). Groups of mice (n = 3/time point) were euthanized at 5, 20, 60, and 120 min([99mTc]GVs) or at 30, 60, 240, and 360 min ([99mTc]Tz). Tissues and fluids were then collected and activity counted. a The uptake of [99mTc]GVs was mainly found in the gall bladder, liver, lungs, small intestine, spleen, and bladder. b In contrast, [99mTc]Tz was mainly found in the gall bladder, small intestine, large intestine and cecum, and bladder. Data are reported in % injected dose (ID)/g ± SEM.
