Time-dependent changes in intracellular levels of radioactivity in (A) TK6 cells and (B) TK1-deficient TK6-2 cells incubated for up to 120min in [H-3]FLT (●), cells preloaded by incubation in [H-3]FLT for 60min, then washed and cultured in [H-3]FLT-free buffer for up to an additional 120 min (○), and cells incubated with [H-3]TdR (x). Solid line: Average initial [H-3]FLT activity in equivalent volume of buffer ± 1sd around average (dashed lines).
