(A) Composite 2D image of x-ray scattering from helium, capillary, buffer, and protein solution (quadrants 1–4, respectively). An enlarged view of the SAXS region is shown in the corner of quadrant 1. The protein concentration was ∼50 mg/mL. (B) Angular integration of experimental scattering images in A with the detector pixels binned into annular rings spaced by 0.01 Å^-1. (C) Decomposition of the protein solution scattering pattern into its respective contributions. Note the log–log scale.
