Determining the optimal Ag concentration to be used for bead coating and the optimal serum dilution. The figure shows MFI values obtained from the serum of an exposed adult from Dielmo village at seven different dilutions (from 1:50 to 1:3200) with beads coated with three concentrations (0.075, 0.3 and 1.2 nmol) of synthetic peptides. All peptides were detected by the tested serum and their signals were much higher than the background signal against BSA-coated beads (upper left graph).
