Intensity particle size distribution spectra of bovine insulin: (A) Absence and (B) Presence of 350 µM NK9 (NK9 : insulin = 1

<p>∶<b>1).</b> Each spectrum is an average of 36 scans. The figure shows the results of dynamic light scattering analysis as a function of incubation time. Panel C shows hydrodynamic radius of 350 μM insulin, in presence and absence of NK9 at different times of incubation at fibrillation inducing environment. Filled square represents insulin and open circle represents insulin in presence of NK9. Each DLS measurement is an average of 36 scans and the error bar represents the standard deviation of those 36 measurements.
