Characterization of Dox@iRGD-Exos-131I. A The main composition of the EGFP-C1-iRGD-Tyr7-Lamp2b plasmid and an image of iRGD/blank-Tyr7-EGFP-293T cells using fluorescence microscopy (scale bar = 100 μm). Representative TEM images and particle size distribution of B blank-Exos, C iRGD-Exos, E blank-Exos-131I, F iRGD-Exos-131I and G Dox@iRGD-Exos-131I (scale bar = 200 nm). D Western blotting analysis of exosome marker proteins (TSG101, CD9 and Alix) of blank-Exos and iRGD-Exos
