Figure 3. Cellular uptake of ^99mTc-DMEOP, ^99mTc-TMEOP, ^99mTc-Sestamibi, and ^99mTc-tetrofosmin in several human cancer cell lines, represented as the percentage of cell-associated radioactivity normalized to 10⁶ cells over time. The results presented were calculated from independent biological replicates (n = 3-8) and are given as the average ± SEM
