SAXS of monomeric apoA-IV.
A, scattering function and Guinier plot (inset). B, pairwise distance distribution function. a.u., arbitrary units. C, averaged ab initio reconstruction of monomeric apoA-IV (spheres) and superimposed onto the apoA-IVWT dimer reconstruction (mesh). D and E, DMPC clearance assay comparing isolated monomeric and dimeric forms of apoA-IV (D) and comparing the dimeric form of various mutants with apoA-IVWT (E).
