The X-ray scattering data (I(s) vs s, where s = 4πsinθ/λ and 2θ is the scattering angle; λ = 0.1488 nm) were acquired using a two-dimension position-sensitive MARR-CCD detector and a sample-to-detector distance of ~1000 mm, corresponding to the q-range 0 < q < 0.35. In order to checking for protein aggregation or concentration-dependent effects, samples were prepared at various protein concentrations (2.5 mg/mL, 3 mg/mL and 5 mg/mL) in the buffer 25 mM Tris-HCl (pH 7.5), containing 150 mM NaCl, 2 mM EDTA and 1 mM β-mercaptoethanol. Samples were exposed to X-ray at different time frames (5 x 30 seconds, and 180 seconds) to investigate for X-ray damage. No radiation damage or concentration-dependent effect were observed. The model depicts the averaged spatial representation of the protein (DAMFILT occupancy and volume-corrected bead model).","tags":[],"intensity_unit":null,"experimental_mw":21.0,"experimental_mw_error":null,"guinier_i0_mw":null,"guinier_i0_mw_error":null,"porod_mw":null,"porod_mw_error":null,"pddf_i0":0.01292,"pddf_i0_error":0.000139,"guinier_i0":0.012933,"guinier_i0_error":7.5e-05,"pddf_rg":2.55,"pddf_rg_error":0.03,"guinier_rg":2.47,"guinier_rg_error":0.09,"pddf_dmax":8.5,"pddf_dmax_error":5.0,"porod_volume":null,"porod_volume_error":null,"estimated_volume":null,"estimated_volume_error":null,"guinier_point_first":1,"guinier_point_last":29,"pddf_point_first":null,"pddf_point_last":null,"i0_calibration_standard_data":null,"intensities_log_log_plot":"SASDC55_datloglog_img.png","symmetry":null,"last_modified":"2019-12-06T13:07:15.624532+01:00","bragg_peak":[]}
