data from solutions of
Calcium binding domains 1 and 2 from sodium-calcium exchanger 1.4, calcium-bound state
in
20 mM Tris-HCl, 100 mM KCl, 20 mM -mercaptoethanol, 10 mM CaCl2, pH 7.2
were collected
on the
EMBL X33 beam line
at the DORIS III, DESY storage ring
(Hamburg, Germany)
using a Pilatus 1M-W 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 10 mg/ml were measured
at 5°C.
10 successive
2 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.
