Protein A production by Staphylococcus aureus. (A) Protein A secretion is higher in S. aureus strains Newman and USA300 compared to S. aureus strains M116 and RN6390, as determined by an ELISA assay (n = 5). (B) More Protein A is bound to the surface of S. aureus strains Newman and USA300 compared to S. aureus strains M116 and RN6390, as determined by FACS (n = 3). (C) Amount of Protein A bound to the surface of S. aureus measured on 2.5, 3.5, and 24 h as determined by FACS. Except for strain RN6390, the amount of surface bound Protein A is increasing over time (n = 3, neutrophils derived from three individual donors).
