of perivitellin-2 (PcPV2) in 20 mM Tris-HCl, pH 8.5 on the D02A-SAXS2 Beamline at the Laboratorio Nacional de Luz Sincrotron (LNLS, Campinas, Brazil) using a MAR Image Plate detector (I(s) vs s, where s = 4π sin θ/λ, 2θ is the scattering angle and λ the X-ray wavelength, 0.155 nm). Different solute concentrations in the range 0.60-2.40 mg/ml were measured. Five successive 300 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 and the different curves were scaled for protein concentration. The low angle data collected were obtained from a single concentration scattering curve. PcPV2 is an oligomeric protein of 400kDa composed of the perivitellin-2 31 kDa and perivitellin-2 67 kDa subunits.","tags":[],"intensity_unit":null,"experimental_mw":400.0,"experimental_mw_error":null,"guinier_i0_mw":null,"guinier_i0_mw_error":null,"porod_mw":null,"porod_mw_error":null,"pddf_i0":0.0004835,"pddf_i0_error":null,"guinier_i0":0.00049,"guinier_i0_error":null,"pddf_rg":4.86,"pddf_rg_error":0.009,"guinier_rg":4.84,"guinier_rg_error":0.18,"pddf_dmax":16.96,"pddf_dmax_error":null,"porod_volume":294.0,"porod_volume_error":null,"estimated_volume":null,"estimated_volume_error":null,"guinier_point_first":3,"guinier_point_last":20,"pddf_point_first":null,"pddf_point_last":null,"i0_calibration_standard_data":null,"intensities_log_log_plot":"SASDBX4_datloglog_img.png","symmetry":null,"last_modified":"2019-12-06T13:07:15.624532+01:00","bragg_peak":[]}
