Table 1. The hydrodynamic radius (R_H) of the proteins calculated from DLS, Native gel, SEC and SAXS experiments.

Protein	Calculated RH (Å)
	DLS	Native Gel	Gel Filtration	SAXS †
hPPARγ LBD monomer	27.5	N/C*	28.0	27.4
hPPARγ-hRXRα LBD	39.0	39.0	39.0	36.7
hRXRα LBD dimer	38.0	38.0	36.0	-----------
hRXRα LBD tetramer	43.0	43.0	42.0	-----------

^† R_H calculated from R_g (Guinier analysis) using the relation between them: R_H = R_g×1.3.
