Synchrotron SAXS
data from solutions of
Calcium-gelsolin and the F-form of actin at a 1:2 molar ratio from high to low ionic strength
in
2 mM Tris-Cl, pH 8.0, 0.2 mM ATP, 1 mM NaN3, 0.1 mM CaCl2, 0.5 mM DTT, pH 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 = 0.155 nm
(I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle).
One solute concentration of 2.00 mg/ml was 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.
