Fig 3. Quantification of PARPi-FL uptake after irradiation.

Fig 3

Specific uptake of PARPi-FL into FaDu (A) and Cal27 (B) cells was determined by flow cytometry after incubation of cells with PARPi-FL or Olaparib/PARPi-FL. Olaparib competes with PARPi-FL for specific binding sites on PARP1. PARPi-FL uptake of FaDu (C) and Cal27 cells (D) after irradiation with 2, 4 and 10 Gy was determined and compared to 0 Gy. Mean PARPi-FL fluorescence signal was measured via flow cytometry in the FITC channel. Bars represent means ± SEM from three independent experiments with three parallels each.
