Figure 5From: Structural analysis and insertion study reveal the ideal sites for surface displaying foreign peptides on a betanodavirus-like particle Purification of HV by nickel-based affinity chromatography . A SDS-PAGE and immunoblotting (IB) of purified HV and RBS. M represents protein marker and the HCP bands are indicated by an arrow. 2× RBS meant that the loading volume of RBS was two folds of those of other HV. B EM of chromatography-purified HV. The bar indicates 100 nm.Back to article page
