Synchrotron SAXS
data from solutions of
RAR/RXR heterodimer : BMS493 : IR0 element
in
20 mM Tris HCl, 75 mM NaCl, 75 mM KCl, 2 mM CHAPS, 4 mM MgCl₂, 12 mM TCEP, pH 7.5
were collected
on the
SWING beam line
at the SOLEIL storage ring
(Saint-Aubin, France)
using a Eiger 4M detector
at a sample-detector distance of 2 m and
at a wavelength of λ = 0.10332 nm
(I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle).
In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 50.00 μl sample
at 10 mg/ml was injected at a 0.20 ml/min flow rate
onto a GE Superdex 200 Increase 10/300 column
at 15°C.
990 successive
1.990 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.
