By employing the above described approach we can demonstrate that the material properties of the growth signal following Proteinase K incubation is similar to the non-treated fibrils (Fig. ) and show that the primary mass deposited to the surface is fib-rillar in nature in all growth phases. We find no indication that monomer binding accounts for a significant fraction of the deposited material in any of the measurements as the DF response is effectively continuous between each growth phase (ignoring the first minute of solution volume exchange). Furthermore, we find that the frequency dependence on overtones are comparable between the shaven and non-shaven fibrils, further demonstrating that the nature of the deposited material is similar between the samples (Fig. ).
