  "experiment_description": "Synchrotron SAXS data from solutions of HTT1 peptide in sodium phosphate buffer, pH 7.4 were collected on the TPS13A beam line at the NSRRC (Hsinchu, Taiwan) using a Eiger X 1M & 9M detector at a sample-detector distance of 2.5 m and at a wavelength of λ = 0.08265 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 4 and 8 mg/ml were measured at 10°C. Three successive 2 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted. The low angle data collected at lower concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.",
