Assessment of performance of protein chips in detection of multiple bacterial species Left Upper line: Scheme of antibodies spotted in the x, y axis. Yellow: anti-E. coli Antibodies; orange: anti-Salmonella Abs; black: anti-C. jejuni Abs; green: anti-Listeria monocytogenes Abs; red: anti-S. aureus Abs. Size of the subarray area is 3 × 3 mm. Salmonella spp. were recognised by anti-Salmonella specific antibodies (b); E. coli (a) was detected in the anti-E.coli Ab spots. (c) C. jejuni was recognised by anti-C. jejuni Abs; (d) Listeria monocytogenes was recognised by anti-Listeria Abs; (e) Staphylococcus aureus was recognised by anti-S. aureus Abs. Experiments were repeated at least three times. Scale in mm. Each subarray area was 3 × 3 mm.
