Characterization of influenza A nucleoprotein (NP) constructs. (A) Size distribution as measured by dynamic light scattering (left panel). The x-axis shows a distribution of size classes (nm) and the y-axis shows the relative volume distribution. Hydrodynamic diameters are obtained from scattering intensity DLS distributions. (B) Thermal stability as measured by nano differential scanning fluorimetry (right panel). The inflection temperature (Ti) values are mentioned. (C) Electron microscopy images. NP protein vaccines show different oligomeric states.
