experiment_descriptionSynchrotron SAXS data from solutions of the ternary complex of the FcRn ectodomain, FcRn binding optimised human serum albumin and the human growth hormone derivative somapacitan in 100 mM MES, 100 mM NaCl, pH 6.5 were collected on the I911-4 beam line at MAX IV (Lund, Sweden) using a Pilatus 1M detector at a wavelength of λ = 0.1 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 4.5 mg/ml was measured at 25°C. One 120 second frame was collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.

One solute concentration of 4.5 mg/ml was measured at 25°C. One 120 second frame was collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.",
