Figure 8. Uptake of aptamer-Dox conjugate on the Y79 cell line post 12 h addition in vitro. Free Dox, EpDT3-Dox, and Scr-EpDT3-Dox were incubated with Y79 cells for 12 h and observed under an AxioObserver microscope. Panels A, B, C, and D: are phase images of Y79 cells unstained, treated with free Dox, Scr-EpDT3-Dox or Scr-EpDT3-Dox, and the respective right panel to it is fluorescent image merged.
