WebA comparison of the hydrodynamic radius to other types of radii can be shown using lysozyme as an example (see Figure 2). molecular weight of the protein is 14.7 kDa, with a partial specific volume or inverse density of 0.73 mL/g. The radius of gyration (R g) is defined by the expression given below, where m i is the mass of the i Webmean square radius of gyration, Os 2P0 . In previous studies of a s , Horita et al. paid particular attention to its correct determination by choosing a pair of good h-solvents so that the values of the unperturbed Os 2P0 in the solvents coincided with those of Os 2P0 in the h-solvent, which was taken as a reference [24].

"WebNov 15, 2012 · The characteristic Rg/Rh value for a globular protein is ~0.775, which means that Rg is smaller than Rh. However, when molecules deviate from globular to non-spherical or elongated structures then Rg/Rh tend to values upwards of 0.775, as Rg becomes larger than Rh. Experimentally, it is important to remember that for proteins Rg cannot be ... " - Flory radius vs radius of gyration
