Figure 2From: Expression of citrulline and homocitrulline residues in the lungs of non-smokers and smokers: implications for autoimmunity in rheumatoid arthritis Citrullination occurs in several human organs. Representative immunoblot with (A) AMC, (B) anti-PAD2 and (C) anti-PAD4 antibodies on proteins (20 μg/lane) from one COPD lung tissue lysate (lane 1) and control tissue lysates from lymph node (lane 2), liver (lane 3), kidney (lane 4), spleen (lane 5), ovary (lane 6), heart (lane 7) and skeletal muscle (lane 8). AMC, anti-modified citrulline; COPD, chronic obstructive pulmonary disease; PAD, peptidylarginine deiminase.Back to article page
