Time-dependent uptake and differences in localization pattern. Confocal images of live CHO-K1 cells incubated with (A) Oct4-PTD or (B) Penetratin for 15, 30 or 60 min at 37°C. Peptides were applied at a final concentration of 5 μM in serum free medium. Laser and photomultiplier settings were kept constant during the entire experiment; intensities are therefore comparable.
