A. Peptides are named according to their RgpA source and approximate molecular weights. Individual peptides were expressed as recombinant His-tag fusions in E. coli BL21.

B. Binding of native and r-A44 peptides to fibronectin and fibrinogen was measured by ELISA using anti-A44 specific primary and HRP-conjugated secondary antibodies. Key: Inline graphic r-A44 binding to fibrinogen; Inline graphic n-A44 binding to fibrinogen; Inline graphic r-A44 binding to fibronectin; Inline graphic n-A44 binding to fibronectin.
