Synchrotron SAXS
data from solutions of
Nuclear fragile X mental retardation-interacting protein 2 (FRMP)
in
50 mM Tris-HCl pH 8.0, 5 mM TCEP
were collected
on the
EMBL X33 beam line
at the DORIS III, DESY storage ring
(Hamburg, Germany)
using a MAR 345 Image Plate detector
at a sample-detector distance of 2.7 m and
at a wavelength of λ = 0.15 nm
(I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle).
Solute concentrations ranging between 2 and 6 mg/ml were measured
at 25°C.
Two successive
120 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.
The low angle data collected at lower concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.
