at a wavelength of λ = 0.1 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Co-flow in-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 50.00 μl sample at 6.5 mg/ml was injected at a 0.40 ml/min flow rate onto a GE Superdex 75 Increase 5/150 column at 21°C. 641 successive 1 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.","tags":[],"intensity_unit":"arbitrary","experimental_mw":59.5,"experimental_mw_error":null,"guinier_i0_mw":null,"guinier_i0_mw_error":null,"porod_mw":61.0,"porod_mw_error":null,"pddf_i0":0.01324,"pddf_i0_error":null,"guinier_i0":0.0132282,"guinier_i0_error":null,"pddf_rg":2.83,"pddf_rg_error":null,"guinier_rg":2.802,"guinier_rg_error":0.097,"pddf_dmax":9.3,"pddf_dmax_error":null,"porod_volume":99.0,"porod_volume_error":null,"estimated_volume":null,"estimated_volume_error":null,"guinier_point_first":7,"guinier_point_last":76,"pddf_point_first":null,"pddf_point_last":null,"i0_calibration_standard_data":null,"intensities_log_log_plot":"SASDX74_datloglog_img.png","symmetry":null,"last_modified":"2026-03-25T10:08:43.411933+01:00","bragg_peak":[]}
