In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 70.00 μl sample at 10 mg/ml was injected at a 0.35 ml/min flow rate onto a Agilent Bio SEC-3, 300 Å column at 10°C. 10 successive 2 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":"1/cm","experimental_mw":9.6,"experimental_mw_error":null,"guinier_i0_mw":null,"guinier_i0_mw_error":null,"porod_mw":null,"porod_mw_error":null,"pddf_i0":null,"pddf_i0_error":null,"guinier_i0":0.00896054,"guinier_i0_error":null,"pddf_rg":null,"pddf_rg_error":null,"guinier_rg":1.5,"guinier_rg_error":0.16,"pddf_dmax":6.0,"pddf_dmax_error":null,"porod_volume":4.0,"porod_volume_error":null,"estimated_volume":null,"estimated_volume_error":null,"guinier_point_first":2,"guinier_point_last":145,"pddf_point_first":null,"pddf_point_last":null,"i0_calibration_standard_data":null,"intensities_log_log_plot":"SASDVP5_datloglog_img.png","symmetry":null,"last_modified":"2024-08-18T16:49:40.771112+02:00","bragg_peak":[]}
