Result

Type of curve: single_conc
Comments: Sample of GluA2 in the resting state (apo). The SANS data were fitted with a mixture of GluA2 in the tetrameric resting state (pdb-code 4u2p) and a fraction of oligomers of the tetramer (best fit: fit54.dat). The oligomers were described with a fractal structure factor (Teixeira, J. (1988). J. Appl. Crystallogr. 21, 781-785). Data were fitted with WillItFit (Pedersen, M. C., Arleth, L. & Mortensen, K. (2013). J. Appl. Crystallogr. 46, 1894-1898). The SANS data were measured in three settings (sample/collimation): 1.5m/4m, 4m/4m, and 8m/8m. The attached data are merged into one data set with all three settings. Pair distance distribution functions were calculated with BayesApp (www.bayesapp.org). Due to relatively low protein concentration, the concentration measurement was inaccurate, and the MW was therefore evaluated by (concentration independent) Porod analysis using the Porod volume calculator implemented in PRIMUS, and with a volume-to-mass conversion constant of 0.83 kDa/nm^3 (Gekko, K. & Noguchi, H. (1979). J. Phys. Chem. 83, 2706-2714; Squire, P. G. & Himmel, M. E. (1979). Arch. Biochem. Biophys. 196, 165-177).
