"experiment_description": "Synchrotron SAXS data from solutions of HTT0 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). In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 70.00 μl sample at 10 mg/ml was injected at a 0.35 ml/min flow rate onto a Agilent Bio SEC-3, 300 Å column at 10°C. 10 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.",
