Fig. (7) dD/dF ratios (Primary X [bottom] and Y axis [black, left]) and dF values (secondary Y axis [ultrafine dotted; right] and the secondary X [ultrafine dotted; top]) for binding of VCP, tVCP, Cur and C3b on gold surface are as shown in this figure. dD/dF ratios at 30 min interval are shown by solid black bars whereas final dD/dF ratios are shown by hatched bars. The dF₃₀ values are shown by gradient black bars whereas the final dF values are shown by a black hatched line with gradient black dots (). dD/dF ratios and dF values indicate an average of the values obtained from two experiments unless specified in the Table 1.
