Fig. 6: Delivery of protein cargoes in different mammalian cell lines and plants.

a Confocal microscopy images of four mammalian cell lines treated with 1.5 µM UbcH786C+-T or UbcH786C-T in the presence of TAT3 for 30 minutes at 37 °C. The images shown are representative of independent biological replicates (n = 3). b Scheme showing the architecture of plant cells and the workflow of plant infiltration. c Representative images of protein cargoes delivery into A. thaliana and N. tabacum leaves after treatment with QSY21-NHS. The images shown are representative of independent biological replicates (n = 3). Scale bars, 20 µm.
