Fig. 4From: The Evolutionarily Conserved Ribosomal Protein L23 and the Cationic Urease β-Subunit of Yersinia enterocolitica O:3 Belong to the Immunodominant Antigens in Yersinia-Triggered Reactive Arthritis: Implications for AutoimmunityBinding of the urease β-subunit (Uβ) derived peptides to HLA-B27, measured by densitometry of the [35S]-methionine-labeled B27 heavy chainColumn 2 represents the relative binding affinity of the control peptide HIV gag 265–276, which has been defined as an intermediate binder (26). Dotted lines are drawn at optical densities/mm2 × 2 and × 4 higher in the peptide treated lysates than in lysates treated with PBS instead of peptide.Back to article page
