Identification of vesicles in the P200 fraction. (a) Experimental scheme for serial centrifugations to isolate sub-fractions (b,b’) Representative TEM images of (b) the P100 and (b’) P200 fraction from HEK293 CM. (c,c’) Representative ESEM images of (c) the P100 and (c’) P200 fractions from HEK293CM. (d) Histograms for the size distribution of particles in the P100 (blue) and P200 (red) fractions from TEM images of HEK293 CM in (b,b’) (n = 500). (e) Histograms for the size distribution and concentrations of particles in the P100 (blue) and P200 (red) fractions analyzed by NTA. Scale bar: 100 nm
