Comparative uptake of [³H]gemcitabine and incorporation into nucleic acids of RL-7 and RL-G cells. (A) Cells were exposed to [³H]gemcitabine for 2–60 s. (B) Accumulation of [³H]gemcitabine in RL-7 and RL-G cells over a 4 h exposure period. Each time point represents the average (± S.D.) of three determinations (C) Incorporation of [³H]gemcitabine (pmol/mg) into nucleic acids after a 4-h exposure in two separate experiments.
