From: Molecular characterization of exosome-like vesicles from breast cancer cells
Characterization of morphology and protein content of exosome-like vesicles. A) MCF-Exo and MDA-Exo were negatively stained using uranyl acetate and viewed by electron microscopy. Inside images are with higher magnification, the scale bar represents 500 nm. B) Identified peptide targets exclusively expressed in MCF-Exo or (C) MDA-Exo. The peptide targets were identified using Mascot protein database. The score is the probability of an overlap between the peptide feature and Mascot database (p < 0.05).
