Small-angle neutron scattering (SANS) data from solutions of Nanolipoprotein Particle (NLP) from In Vitro Assembly in PBS constituted in 42% D2O, pH/D 7.4, were collected on the NGB30 instrument at the NIST Center for Neutron Research (Gaithersburg, MD, USA) using a 640x640 mm 3He posn sensitive Ordela 2660N detector at a wavelength of λ = 0.6 nm (I(s) vs s, where s = 4πsinθ/λ and 2θ is the scattering angle). One solute concentration of 0.96 mg/ml was measured at 25°C. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
Additional SANS measurement parameters. Two detector positions (in m) and count times (s) were employed: 1.33 m (two frames of 900 + 831 = 1731 s total count time); 4 m (two frames of 3600 + 3600 = 7200 s total count time).
