Synchrotron SAXS
data from solutions of
Ethylene Receptor 1 Cytosolic Domain
in
20 mM TRIS 150 mM NaCl 1mM DTT 250mM NDSB, pH 8.8
were collected
on the
EMBL P12 beam line
at the PETRA III storage ring
(DESY; Hamburg, Germany)
using a Pilatus 2M detector
at a sample-detector distance of 3.1 m and
at a wavelength of λ = 1.24 nm
(I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle).
Solute concentrations ranging between 0.7 and 4.2 mg/ml were measured
at 10°C.
20 successive
0.050 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.
