Fig. (9) dF values for the interaction of VCP and tVCP adsorbed either on the gold or ps surfaces with C3b ( X-axis) were plotted against dD values (Y-axis). The data label for each series indicates AMs (Series: C3b-VCPps, C3b-VCP, C3b-tVCPps, and C3b-tVCPg indicate adsorption of C3b on VCPps, VCPg, tVCPps, and tVCPg.
