Fig. 1 — Wild-type particles (wt CPMV) and particles displaying the p524opt peptide (CPMV.p524opt) were characterized and compared after purification from N. benthamiana leaves. Gel electrophoresis under denaturing conditions was followed by (A) silver staining and (B) Western blot analysis to assess the purity of the particles. The small subunit (S) and large subunit (L) were detected in both cases. The structural conformation of the purified particles was confirmed by TEM (C and D) and DLS analysis (E).
