FIG. 1.

Scattergram showing 80 human sera (IgG) in different clinical categories tested against three recombinant proteins by ELISA. (A) rSfbI; (B) rSfbII; (C) rSfbII lacking the C-terminal fibronectin binding repeat region. Sera were diluted to 1:100 and titers were measured by the reading for the optical density (OD) at 655 nm. Each symbol represents one serum sample.
