Decoration of engineered OMVs with heterologous S. aureus antigens. (A) Schematic representation of the selection of the recombinant S. aureus antigen stEsxA, stSbi and stSpA. (B) Western blot analysis of OMVsc bond with heterologous recombinant S. aureus antigens by using an anti-His6 primary antibody. The red arrow indicates the trOmpA-antigen conjugations and the black arrow indicates the trOmpA-SpyCather fusion protein.
