SDS-PAGE protein profile of OMVs purified from B. suis, B. ovis, B. canis, and B. neotomae. OMVs were purified by differential centrifugation and loaded onto a 15% acrylamide gel for electrophoresis. MWM, molecular weight marker. Lane 1: protein profile of OMVs purified from B. suis ATCC 23444. Lane 2: protein profile of OMVs purified from B. ovis ATCC 25840. Lane 3: protein profile of OMVs purified from B. canis ATCC 23365. Lane 4: protein profile of OMVs purified from B. neotomae ATCC 23459. One hundred micrograms of OMV proteins were loaded into each well
