Synchrotron SAXS data from solutions of Insulin glargine (Lantus ®), oligomeric mixture in Lantus Formulation (30 µg Zinc cloride, 2.7 mg m-Cresol, 20 mg glycerol 85%), pH 4 were collected on the EMBL P12 beam line at the PETRA III storage ring (Hamburg, Germany) using a Pilatus 2M detector at a sample-detector distance of 3.1 m and at a wavelength of λ = 1.241 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 3.64 mg/ml was measured at 20°C. 20 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.
