Fig. 1From: Comparative proteomic profiling of plasma exosomes in lung cancer cases of liver and brain metastasisCharacterization of the plasma-stemming exosomes. A Experimental workflow showed the isolation and proteomic analyses of plasma-stemming exosomes. B TEM showed the shape of plasma-stemming exosomes. The bar indicates 100Â nm. C NTA showed the size distribution of plasma-stemming exosomes. D WB detected the exosome-based surface marker proteins CD9 and CD81Back to article page
