IgG response of rheumatoid arthritis sera to noncitrullinated and citrullinated linear peptides. The IgG response of the 110 rheumatoid arthritis sera to noncitrullinated (NC) and citrullinated (C) linear peptides was detected using Luminex technology. These peptides derived from α-enolase (YNQLLR_citrIEEELGSKAK) and from far upstream element-binding protein (FUSE-BP) (VPDGMVGFIIGR_citrGGEQISR). FUSE-BP, far-upstream element-binding protein.
