Figure 3.

Protein mass spectra collected on CM10 and IMAC-Cu²⁺ ProteinChip arrays with serum samples provided by five patients with arthritidies (including rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis) and five noninflammatory controls (NIC) (including osteoarthritis). (a) The inflammatory-related proteins S100A8, S100A12, S100A9, and one of its variant S100A9* are arthritis biomarkers detected on CM10 arrays. (b) On IMAC-Cu²⁺ ProteinChip arrays, SAA and its 2 variants (SAA-R and SAA-RS) are illustrated, reproduced from [19].
