The diffusion times before (τD1) and after (τD2) treatment with 6 M urea at 50°C, diffusion coefficient (D1), hydrodynamic radii in the absence (RhD1) and presence (RhD2) of 6 M urea at 50°C, as well as, the number of fluorescent moieties (Nf) present in the EGFP-VP2, EGFP-VP2-14, EGFP-VP2-23 and EGFP-VP2-40 fluorescent proteins and VLPs. The enhanced green fluorescent protein (EGFP) served as a reference.
