SLDs for each of the components used in the contrast variation SANS experiments.

Contrast	Protein	Complex	Surfactant	ZAC
SLDhGH/×10−6 Å−2	3.09	3.09	2.31	ZACa
SLDSDS/×10−6 Å−2	6.37	3.09	6.37	6.45
SLDSolv/×10−6 Å−2	6.37	6.37	2.31	ZACb

^aThe SLD of the protein depends on the SLD of the solvent and was calculated for each sample from the contrast-match experiment results.

^bThe SLD of the solvent is calculated using the equation for the ZAC condition (see ESI).
