There are no models related to this curve.

SAXS data from solutions of the basic domain of telomeric repeat-binding factor 2 (TRF2) in 50 mM sodium phosphate, 50 mM NaCl, pH 7, were collected using a Rigaku BioSAXS-1000 instrument at CEITEC (Brno, Czech Republic) equipped with a Pilatus 100K detector at a sample-detector distance of 0.5 m (I(s) vs s, where = 4π sin θ/λ; 2θ is the scattering angle and λ = 0.154 nm). Six successive 3600 second frames were collected at a sample temperature of 4°C using a solute concentration of 1.2 mg/ml. The data were normalized to the intensity of the transmitted beam and radially averaged and the corresponding scattering from the solvent-blank was subtracted to produced the scattering profile displayed in this entry.
