Figure 6.

Sedimentation equilibrium data for peptide 1 (left column) and peptide 8 (right column) are shown at a peptide concentration of 20 μM and rotor speed of 30,000 rpm. The global fit (solid line) to experimental data (open circles) is shown in the middle panels, and the residuals between the calculated concentration distribution and experimental data in the top panels. The lower panels show ln Y versus r² of the experimental data (open circles) compared with the theoretical monomer (m), dimer (d), and trimer (t) single-species plots (solid lines), where y is absorbance, which is proportional to concentration.
