Biophysical characterization of exosomes isolated from MM and colostrum. (a) TEM images of exosomes isolated by OptiPrep density gradient centrifugation revealed vesicles with a morphology similar to exosomes and a diameter in the range of 30–150 nm for all four samples. The colostrum samples had meagrely scattered vesicles with higher protein background whereas the MM samples revealed a rich population of exosomes with typical cup-shaped morphology. (b) NTA revealed peak intensities to be 125, 95, 95 and 145 nm for 24, 48, 72 h colostrum and MM samples, respectively.
