Prevalence of antibodies against deiminated and undeiminated α-enolase in RA patients and healthy controls. Immunoblotting of in vitro citrullinated and untreated α-enolase with serum samples from patients with rheumatoid arthritis (RA) and normal controls, showing that about half of the serum samples from the RA group contain antibodies with selectivity for citrullinated α-enolase.
