Figure 1. Characterization of plasma exosomes.
A) Representative Transmission Electron Microscopy (TEM) image of purified exosomes from plasma using PEG-based solution; scale bar: 200 nm. The histogram represents the distribution of vesicle sizes in the TEM image, with an average size of 36.7nm (dashed red line). (B). Representative NanoSight Tracking Analysis (NTA) graph showing the size (x-axis) and concentration (y-axis) of diluted exosomes (1:1000) in 1x PBS solution. Red shading indicates +/− 1 standard error of the mean.
