Wide-angle scattering curves from hemoglobin using ST data-collection mode. (a) This curve set is a series of measured scattering profiles from a single stationary protein solution, in the exposure order of black/blue/green/red. Note that the trend as the X-ray exposure increased is progressive structure degradation as evidenced by the overall flattening of the curve. (b) Isolation of the first and tenth data sets (black and red, respectively) demonstrates the eventual loss of the quaternary structure-associated peak (black arrow) and a tertiary structure associated peak (red arrow), plus an overall flattening in the secondary structure region spacing (green arrow). The abscissa is in arbitrary units for relative intensity, and the ordinate is in units of Å−1.
