Small and large outer membrane vesicle (OMV) populations purified from a heterogeneous population of OMVs. (a) OMV population diameter sizes (nm) of E. coli BW25113, rfaC knockout (ΔrfaC), rfaG knockout (ΔrfaG), and rfaL knockout (ΔrfaL) strains, respectively, were evaluated using Nanoparticle Tracking Analysis (NTA); (b) average diameter size of E. coli BW25113, rfaC knockout (ΔrfaC), rfaG knockout (ΔrfaG), and rfaL knockout (ΔrfaL) OMVs presented in nm in each concentration (particle/mL). * p < 0.05 and ** p < 0.01 indicate statistical significance.
