Table 3 A summary of the binding of S. aureus polypeptides to immobilized ligands

From: Adhesive polypeptides of Staphylococcus aureus identified using a novel secretion library technique in Escherichia coli

Polypeptide tested ELISA* cell-free supernatant ELISA* purified 6xHis polypeptide SPR† purified 6xHis polypeptide

  1. * Binding of polypeptides to immobilized target molecules by enzyme-linked immunoassay
  2. † Binding of polypeptides to immobilized target molecules by surface plasmon resonance
  3. ‡ C-terminally FLAG-tagged recombinant polypeptide used as positive control in screening of the FTP library
  4. - indicate no binding; ligand in brackets indicate weak binding
  5. ND, indicate not determined. The SCOR and IspD polypeptides could not be produced as 6xHis recombinant polypeptides and the D1-D3 polypeptide was produced into the cell-free growth medium and did not carry a His tag.
