  "experiment_description": "Synchrotron SAXS data from Poly-L-Glutamic Acid (PGLA) in neat dimethyl sulfoxide were collected on the EMBL-P12 beam line at the PETRA III storage ring (Hamburg, Germany) using a Pilatus 2M detector at a wavelength of λ = 0.124 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 10 and 30 mg/ml were measured at 20°C. 40 successive 0.045 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.",
