1. Take the state of the art theories for representing the overall conformation of a globular macromolecule - such as an antibody domain - in terms of the axial ratios a/b, b/c of a general surface inertial ellipsoid of semi axes a,b,c. Do the same for working out the complete hydrodynamic properties of ellipsoids of defined (a/b, b/c) and for bead-shell models of defined bead coordinates. Choose the IgG2 class of antibody. Fit the known crystal structure (stored a pdb file) of the Fab and Fc domains to surface ellipsoids (in terms of a bead-shell array). Measure and fit a bead shell model)2. Check the previously measured sedimentation coefficient, s, for the domains and then measure for the first time an accurate intrinsic viscosity [eta] and harmonic mean rotational relaxation time, tau. Combine this data with 2 to evaluate the molecular hydration of the domains. Then work out a weighted average hydration for the intact molecule, delta. Measure s, [eta] and tau for the intact antibody. Use this, together with the delta, to model the orientation of domains using bead-shell models for the intact antibody, under different solvent conditions.3. Repeat for a range of engineered IgG based antibodies and also IgE to obtain a complete dossier for the IgG and IgE classes of antibody domain orientation as a function of solution and liganded conditions.
