Measurements of peptide 1 and peptide 2 particles

Parameter	Value fora:
	Peptide 1 particles	Peptide 2 particles
Hydrodynamic radius (nm)	2.05	1.47
Polydispersity (nm)b	0.3	0.3
Molecular mass (kDa)c	18.7	6.8

^aPeptide 1 particles form stable trimers at pH 7.35, as revealed by dynamic light scattering. For peptide 1 particles, the mean scattering amplitude of the measurement was 0.798, and the diffusion coefficient was 1,025 cm²/s. For peptide 2 particles, the mean scattering amplitude of the measurement was 0.670, and the diffusion coefficient was 1,434 cm²/s.

^bThe peptide 1 sample is primarily monodisperse, since the polydispersity is 14.0% of the mean hydrodynamic radius. Monomodal analysis yields a baseline of 1.000 and a sum-of-squares value of 0.387. The peptide 2 sample is primarily monodisperse, since the polydispersity is 20.0% of the mean hydrodynamic radius. Monomodal analysis yields a baseline of 1.000 and a sum-of-squares value of 2.726.

^cThe molecular masses of the particles were calculated by applying the volume shape hydration relationship model using a standard curve of globular proteins.
