Synchrotron SAXS data from solutions of procollagen lysyl hydroxylase LH3 in 25 mM HEPES, 200 mM NaCl, pH 8 were measured at 20°C using SEC-SAXS collected on the BM29 beam line at the ESRF storage ring (Grenoble, France) equipped with a Pilatus 1M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.09919 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 3.50 mg/ml was injected onto the column. 75 successive 1 second frames were collected through the sample elution peak and processed using CHROMIXS that included the identification and subtraction of an appropriate solvent-blank.

The sample was injected at a load concentration of 3.5 mg/mL. The SEC column used was a Superdex 200 PC 3.2/300 Increase (GE Healthcare) at a flow rate 0.075 mL/min.
