From: Identification of citrullinated α-enolase as a candidate autoantigen in rheumatoid arthritis
Localisation of α-enolase in synovial membranes. Immunohistochemistry of biopsy sections from patients with osteoarthritis (a) and rheumatoid arthritis (RA) (b) with the goat anti-α-enolase antibody showing expression of α-enolase (stained brown) in cells in the subsynovium of the patient with RA and in endothelial cells in the patient with osteoarthritis. Cell nuclei are counterstained blue.
