Berkeley, CA, USA) using a Pilatus3 X 2M detector at a sample-detector distance of 2.1 m and at a wavelength of λ = 0.1127 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 55.00 μl sample at 6 mg/ml was injected at a 0.65 ml/min flow rate onto a Shodex KW-800 series column at 7°C. 600 successive 3 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":629.7,"experimental_mw_error":null,"guinier_i0_mw":null,"guinier_i0_mw_error":null,"porod_mw":null,"porod_mw_error":null,"pddf_i0":5440.0,"pddf_i0_error":null,"guinier_i0":5291.9,"guinier_i0_error":null,"pddf_rg":7.11,"pddf_rg_error":null,"guinier_rg":6.756,"guinier_rg_error":2.599,"pddf_dmax":25.7,"pddf_dmax_error":null,"porod_volume":1437.0,"porod_volume_error":null,"estimated_volume":null,"estimated_volume_error":null,"guinier_point_first":1,"guinier_point_last":15,"pddf_point_first":null,"pddf_point_last":null,"i0_calibration_standard_data":null,"intensities_log_log_plot":"SASDVU7_datloglog_img.png","symmetry":null,"last_modified":"2025-10-07T11:35:25.964047+02:00","bragg_peak":[]}
