Figure 1 : Assay using 3 μm diameter beads, binding capacity of 14 μg/mg, assay time of 25 mins, 5 x 108 beads/ml.


(A) change in average pulse height, Δip = blue, and bead concentration = green, against concentration of biotinylated analyte, N.B. error bars are plotted but smaller than the symbol on the graph. (B) Example of raw data from an individual experiment, red histogram displays the pulse height (Δip) for a blank sample, the black distribution shows the change in Δip for an analyte concentration of 1 x 10-9 mol dm-3. Overlaid is a schematic (N.B not to exact scale or position) gate size for the monomer, drimer. (C) Plot of percentage of signal of monomer = red, dimer = green, trimer = blue and tetramer = purple.
