Fig. 2. Light-scattering curve of VP22_core in solution as a function of its elution volume. The monomeric molar mass of VP22_core is 14551 g mol⁻¹ and the light-scattering results show that VP22_core is mono-dispersed with an estimated mean molar mass of 26 500±5000 g mol⁻¹. This shows that VP22_core is dimeric in solution. The SDS-PAGE gel of the injected VP22_core sample and the protein ladder (Mark12 Unstained Standard; kDa) is displayed on the left of the elution peak.
