Figure 5 : (A) Distribution of monomer = red, dimer = green, trimer = blue and tetramer = purple. 1 μm avidin modified beads 25 min assay time 6 x 109 beads /ml, binding capacity 20 μg/mg. (B) Distribution of monomer = red, dimer = green, and tetramer = purple using 0.3 μm Streptavidin modified beads 25 min assay time 1 x 1010 beads /ml, binding capacity 4 μg/mg. (C) Distribution of 5mer = blue, 6mer = purple, and 7mer = green and 8mer = red using 0.3 μm Streptavidin modified beads 25 min assay time 1 x 1010 beads /ml binding capacity 4 μg/mg. (D) Correlation, R2 value, plotted along the axis between the increase in aggregate size versus the decrease in monomer signal for the three different bead sizes.
