Uptake of ricinB:QDs is not reduced by inhibition of Rho.(A) Cells were left untreated, or (B) pre-treated with C3 transferase (1 μg/ml), followed by incubation with ricinB:QDs at 37°C for 40 min. Then, the cells were fixed and stained with the appropriate antibodies against the endosomal marker EEA1 (blue) and CD63 (green), respectively. Images include orthogonal views generated from a z-stack of images.
