Correlation between iron regulatory protein (IRP) activity in synovial fluid cells of RA patients with "free" iron (A) and CRP (B). IRP activity was calculated from the ratio of intensity of IRE-IRP complexes in mobility shift assays performed with or without 2-mercaptoethanol. Serum CRP concentrations correlated with IRP activity (p=0.013)
