Fig 4. Inhibition of S. aureus capture by human immunoglobulin (Ig).

Capture of cultured S. aureus strains isolated from clinical samples using FcMBL-beads (Control) was inhibited by adding 1 mg/ml total human Ig (+ Ig, mean: 8%). Depleting Ig in the supernatant of centrifuged clinical samples infected with S. aureus with protein A-coated magnetic beads partially restored the capture (SNT-SA + ProA, man: 23%). ***: p-value < 0.0001.
