(A) Protein profile of S. vesiculosa M7T purified OMVs using 12.5% 1-D SDS-PAGE. Numbers on the left correspond to molecular weight (MW) in thousands. Arrows indicate the two prominent bands detected. (B) Negative-staining micrograph from purified S. vesiculosa M7T OMVs. A double-bilayer vesicle can be observed with an inner layer that corresponds to the plasma membrane (PM) and an outer layer corresponding to the outer membrane (OM). Bar, 50 nm.
