Dose-dependent and time-dependent analysis of transduced proteins. Various concentrations of TAT fusion proteins were added to IMR90 cells for 8 and 10 h, and the presence of transduced protein in the cells were analyzed by western blotting. Lane 1–5, IMR90 cells were treated with 2.5, 5.0, 10.0, 20.0, 40.0 nM TAT fusion proteins for 10 h; Lane 6–10, IMR90 cells were treated with 2.5, 5.0, 10.0, 20.0, 40.0 nM TAT fusion proteins for 8 h; Lane 11, untreated IMR90 cells
