FIG 6.

Recognition of mimivirus proteins by human sera. (A) Representative Western blots of sera from healthy subjects (HS) and rheumatoid arthritis (RA) patients recognizing mimivirus capsid protein L425. (B) Representative Western blots of sera from healthy subjects (HS) and rheumatoid arthritis (RA) patients recognizing mimivirus collagen L71. Sera were diluted 1:4,000. Positions of recombinant L425 and L71 proteins in the blots are shown at the left of each panel using an anti-His₆ antibody (His₆). A 15-kDa fragment of His₆-tagged human GLT25D2 protein was used as a negative control (Neg).
