Validation of proteins identified in OA synovial fluid by MRM analysis. Bar graph representation of the peak area along with the MRM traces for the peptides validated by MRM. (A) Alanyl (membrane) aminopeptidase (ANPEP): AQIINDAFNLASAHK (z = +2, m/z = 806.93); (B) Dickkopf WNT signaling pathway inhibitor 3 (DKK3): DQDGEILLPR (z = +2, m/z = 578.30); (C) Osteoglycin (OGN): DFADIPNLR (z = +2, m/z = 530.77). (OA synovial fluid n = 10, RT: Retention time).
