2.2 Particle characteristics of these Cap-3M2e VLPs

These Cap-3M2e proteins were dialyzed into the assembly buffer (10 mM Tris-HCl, 100 mM NaCl (pH 8.0)) and formed VLPs. The shape, size, size distribution and zeta potential of these Cap-3M2e VLPs were characterized by transmission electron microscopy (TEM) and dynamic light scattering (DLS).
