In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 45.00 μl sample at 5 mg/ml was injected at a 0.30 ml/min flow rate onto a Agilent AdvanceBio SEC 2.7 µm - 130 Å column at 20°C. 600 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":"1/cm","experimental_mw":19.47,"experimental_mw_error":null,"guinier_i0_mw":null,"guinier_i0_mw_error":null,"porod_mw":30.0,"porod_mw_error":null,"pddf_i0":null,"pddf_i0_error":null,"guinier_i0":0.0280077,"guinier_i0_error":null,"pddf_rg":null,"pddf_rg_error":null,"guinier_rg":3.828,"guinier_rg_error":0.192,"pddf_dmax":18.0,"pddf_dmax_error":null,"porod_volume":47.6,"porod_volume_error":null,"estimated_volume":null,"estimated_volume_error":null,"guinier_point_first":1,"guinier_point_last":43,"pddf_point_first":null,"pddf_point_last":null,"i0_calibration_standard_data":null,"intensities_log_log_plot":"SASDVD8_datloglog_img.png","symmetry":null,"last_modified":"2025-02-24T10:52:45.282955+01:00","bragg_peak":[]}
