The results of small angle scattering investigation of protein apoferritin are presented. The sizes and shapes, including those determined by indirect Fourier transform method, are calculated. The pair-distance distribution function for both small angle neutron (SANS) and X-ray small angle scattering (SAXS) are obtained. It is shown that SANS and SAXS methods give similar shape (spherical shell with holes) of apoferritin. At the same time, fits of experimental data for SAXS and SANS curves give a little different sizes and volumes of the molecule. The reasons for these differences are discussed.
