Figure Lengend Snippet: Conjugation of R848 to H1ssF-Cys nanoparticles (A) Representative image of H1ssF-Cys mutant. (B and C) Size (B) and PDI (C) analysis of H1ssF (WT and Cys mutant) using DLS. (D) Schematic for conjugation of R848 to H1ssF-Cys. BALB/c mice ( n = 3–12 across 3–4 experiments depending on the vaccine tested) were vaccinated and NC99 stem-specific Abs were quantified 14 days p.v. (E) BALB/c mice ( n = 3–12 across 3–4 experiments depending on the vaccine tested) were vaccinated and NC99 stem-specific Abs were quantified 14 days p.v. The dotted line indicates the limit of detection for the assay. TT was defined as the highest dilution with an OD 450 greater than three times the assay background. Lines represent the mean ± SEM. (F) Negatively stained TEM images of the conjugated H1ssF-R848. The scale bar lengths are as follows: 50 nm (A and F, left), 10 nm (F, right). Not significant p ≥ 0.05 (not indicated on graph), ∗∗ p ≤ 0.01, ∗∗∗∗ p ≤ 0.0001.
